FIXED? Small regression wrt numbered bookmarks

[pjj]

Thanks a lot for the newest version! Alas, a small regression has been introduced, with regard to numbered bookmark setting via keyboard:
1) I can't remove any bookmark by pressing Ctrl+Shift+number shortcut again
2) I can't change number of any bookmark by pressing Ctrl+Shift+number shortcut if a bookmark with this number already exists (I believe it was possible before -- "old" one was simply removed)
3) I can't "move" any bookmark to another line by pressing Ctrl+Shift+number shortcut if a bookmark with this number already exists -- I must first remove it from its current line

Fixed in v16.21 (Beta 1). Thanks!
