Environment

• TeXstudio: 4.0.1
• Qt: Qt Version 5.15.2, compiled with Qt 5.15.2 R
• OS: Windows 10
• TeX distribution:miktex

Expected behavior

In former versions of the TexStudio, when one started typing a bibtex key after \cite{, a drop-down-list of possible completions appeared. Then moving the cursor en each of this completion showed, in a yellow box, the full bibtex record -- which is useful, when you have multiple entries from the same author. eg. knorr1986, knorr1987, knorr1987a -- you want to make sure you select the right reference.

Actual behavior

The drop-down list appears, but the yellow boxes have disappeared.

How to reproduce

enter a bibtex key after \cite{ (requires a bibfile).
