New-UDTable export is empty (PSU 5.5.1)

Hello,

after an update to version 5.5.1 all the exports from New-UDTable in my apps are empty (csv, pdf, xlsx, all data or filtered data).

The code is like:
New-UDTable -Data $TableData -Columns $TableColumns -ShowSearch -ShowExport -ExportOption @(“XLSX”, “PDF”, “CSV”) -PageSize 50 -ShowPagination

When I create a new page with random data and just “New-UDTable -Data $RandomData -ShowExport”, it works.

There are some older topics, but I could not find anything helpful.

Can someone help me?

When I add “-IncludeInExport” in my column definition, it now works.

I just wonder why it worked before.. There are many, many tables I have to check now.
