Hi Marko,
Greetings from Syncfusion support.
We are able to reproduce the issue when we refresh the Grid with foreignkey columns and enablePersistence enabled in Grid. If this is the case yours then we suggest you to upgrade to latest version of Essential studio version to overcome the mentioned issue.
If the case is not yours then please provide the following details.
- Share the complete Grid code example.
- Share the replication procedure to reproduce the issue.
- Share the Essential Studio version details.
Regards,
Thavasianand S.
