<Unknown Elements> in the Reports section, recovery after a new data download

Dear CyberTracker Team,

We are currently a team of four working on a specific CyberTracker (CT) project in the lab and field.

After each fieldwork session, one of us performs the data download, saves the database with the new data from the day, and processes the export using a Python script to plan the next day’s fieldwork. The person responsible for the data download varies. The MDB and CTX files are stored in a shared folder, which is updated after each day of fieldwork.

3 of us have not encountered any issues. However, one team member is facing a peculiar problem (we are all using CT Classic v3.532). We have tried uninstalling and reinstalling CT on this computer and rebooting it multiple times, but the issue persists.

Here is a description of the problem:

  • Open the latest MDB file from the project.
  • Download the data (new sightings populate the report section, see Screenshot_1.jpg).
  • Save the file with the date of the fieldwork (save as).
  • Reopen the MDB file.
  • Sightings display “Unknown Elements” instead of the expected results (some values are still registered correctly like “Visite” and “PARMAJ?”, see Screenshot_2.jpg). The “Elements” section is missing some elements.
  • If we just send a “test” sighting via our mobile device and download the data, the “Unknown Elements” are resolved and the previous sightings are all displayed.
  • However, some elements do not display the registered values in the appropriate columns. We need to double-click on the element in the sighting, which adds a new column with the correct value, allowing us to delete the “old” column (see Screenshot_3.jpg with the “Site” column).

We found a similar topic:
https://support.cybertracker.org/t/unusual-error-appear/327
However, in our case, no elements have been deleted. We encounter the same issue whether we download data or import a CTX file (from Backup), save the MDB, and reopen it.

Does anyone have any suggestions on how to resolve this issue?

Thank you in advance,

Lauriane



Hi Lauriane,

How are you downloading the data to the PC? Are you using a USB cable or do you use the publish feature?

Are you sure that everyone is using the same MDB file?

Thanks

Hi Justin,

We are only using the publish feature, without a USB cable.
At the end of each day’s fieldwork, we download the data, save the MDB file with the current date and upload it to a shared folder on a Google Drive.
For example: the person in charge of planning for the next day uses the MDB file from 2025-03-27, downloads the data collected on 2025-03-28, saves the MDB file with a filename containing the date 2025-03-28, and finally uploads it to the Drive.
Aso.

Is this a good way to proceed when multiple people are working on the MDB file to download data and plan for the upcoming days?

Thank you for your advice and help,
lauriane

Hi Lauriane,

Is this all done from a single PC?

Could you please send me the file:
\Documents\CyberTracker\System\Logs\Download.txt
?

Thanks!

Hi Justin,
The Download.txt files have been sent to your email address.
Thank you for your help,
