Value in SharePoint list field disappears

[peterdeleu72]

In a SharePoint list I have a checkbox and a choice field with a lookup from another list. I create a new item and when selecting a value from the choice field and then checking the checkbox the value of the choice field is deleted. A video displaying this can be found here: https://webdevignnet-my.sharepoint.com/:v:/g/personal/peter_peterdeleu_be/EbpN1ZesRw5NnnLWa2YqgScBOu...

The list is newly created and has no validation. Tested it with a brand new list on 2 SharePoint tenants: same problem.

Any ideas?

1. Check if there are any workflows, event receivers or custom scripts associated with the list that could be causing the issue. Disable them temporarily and check if the issue still occurs.

2. Check if there are any validation or formatting rules configured for the choice field that could be causing the issue. Disable them temporarily and check if the issue still occurs.

3. Check if there are any permissions or access restrictions that could be causing the issue. Ensure that the user has the necessary permissions to add and modify items in both lists.

4. Try creating a new choice field with a lookup and a checkbox to see if the issue occurs with this new field. If the issue does not occur, there may be a problem with the original choice field.

5. Check if the issue occurs in other browsers or devices. If the issue only occurs in a specific browser or device, there may be a problem with the browser or device.

@jaortizgolf78 it's a brand new list. Nothing special, just added the fields. I can reproduce it everytime.

Tested in Chrome and Edge
