Hi Felix,

I tested by running Demos\EndUser\ReportExplorer project. I created a new report with a Crosstab. I'm using the Cross tab designer to add and remove column definitions. I do not encounter any issues removing columns.

I use RB 23.04 for testing.

Try running Demos\EndUser\ReportExplorer and create a test cross tab report. If you can create a repeatable test case, save the report to .rtm file and send to support@ along with specific steps to recreate the error.
