Error read/write Siemens Tag

Thank you for the help.
If Ignition will be the only application writing the values (in the future).
Is there a way to correct the values in the PLC without opening the actual PLC program?
For example, if we first empty the string and then start writing them with Ignition.

I’d expect writing new string values from Ignition to correct the issue as long as whatever other process that wrote incorrect values doesn’t do it again.

I can confirm that writing an empty string will resolve the problem.
