Created attachment 183944 [details] Open the document, execute the report. 0 won't be shown in "TID" Open the attached database. Execute the report. Fields for "Town_ID" and "TID" have same datasource. "TID" isn't shown if it is '0'. "Town_ID" (and "ID") had been set to Format Code → 0 "TID" has Format Code → Standard Standard should have a code like 0,## - but it seems to have a code like #,##. So 0-values won't be shown. This is a very old bug. Think it never worked in another way… tested with OpenSUSE 15.3 and LO 7.4.3.2
