Seems that sometimes hitting keys on titler tool changes Kdenlive options.
on 20.xx this year i noticed a lot of time the changes of options after adding/creating a title... usually i have a switching from NORMAL MODE to OVERWRITE MODE (there are no hotkeys for this.. if i'm right)
probably is some combination of keys... like SHIFT+O (overwrite?) but i'm not able to reproduce it
no idea if this is only Windows related.
