The biblatex settings dialog enters some undefined state when one - chooses Style engine Biblatex - changes, for example, Biblatex bibliography style field to some other value - presses either of the two Reset buttons or Match
The other style (in this example Biblatex citation style) dropdown menu becomes inactive, i.e. it shows no items, and pressing the Reset button gives unpredictable results in exported latex code. Can anyone confirm this?
