FlexDash-Unable to Move Widgets around in Dashboard

General
3

Have been facing some other issues too. like some times the FOCUS of the selected widget moves and not the actual widget. some times i cant see the edit panel at all (in which the move widget arrows are there) and it is random, i cant replicate when required.
Edit : and the issue of widget not deployed upon browser refresh, which i raised in another post still exists. Custom FD Widget not (remain) deployed

I found some thing in red font in the browser, when i click MOVE arrow, pasting below
