libreoffice 6.0.1.1 (x64) calc windows

Autofilter function on a field with a lot of text in it not working. Dialog box appears, but I cannot type in the filter text box. It just shows blanks and mouse pointer changes to hourglass.

Autofilter on a field where there isn’t too much text works fine.

It worked without problem before upgrade to this version. Spreadsheet has cca 13000 rows.

Can anybody tell what could be causing it?

Thank you.
