Actions button is not working properly

[Julienec]

I need your help. I have a 'Cancel' button that is enabled whenever the Request Status is 'Pending.' When the 'Cancel' button is clicked, the Request Status should change to 'Cancelled.' However, after clicking the 'Cancel' button, the status correctly updates to 'Cancelled' but then reverts back to 'Pending' after a few seconds. 

Actions config:

Actions' Only if this condition is true : AND(ISBLANK([action]), [Request Status] = "Pending")

[action] is the placeholder for generated file. so this formula says that is the [action] is null and [request status] is still pending

Are there any bots that are configured to execute on updates to the table?

[Julienec]

No, the app don't have any bots, events, processes and task configured. Only 'Behavior' Actions is configured.

Does the column value change in the data source?

Does the data source allow updates?

[Julienec]

The data source allows updates. I don't know why it was revert back to previous 'Request status' value (which is the Pending)
