Since we upgraded confluence server to 6.9.0, when a table (with table head) is put inside an expand, the first data row (so the row after the table head) becomes unselectable and acts as a sorter when clicked on (like an actual head). All our tables inside expands act like this since the upgrade. The editor confirms those rows really shouldn't be table headers though.
Working workaround is adding a row above that row (which then gets that behaviour), but it is still very annoying and for documents that need to be exported from time to time this workaround isn't really possible as this extra row also shows up in the pdf.
Is there any other way to solve this?
