Apparently Monik considers some endgames as draws by insufficient material and thus gets forfeited by the GUI (Cute Chess) when attempting to claim draw. KBKB is one such endgame, e.g.:
8/8/3k4/8/3bB1K1/7p/8/8 w - - 0 160
This is a position from an actual game Monik lost with Black during the ongoing 40/40 gauntlet. Making it play from that position we can see why:

Despite draw being the most likely outcome this is not a draw by insufficient material since theoretically either side could get mated. Here's one legal position that can arise after some moves from the previous position:
8/8/8/8/4B3/8/5K1b/7k b - - 0 1
Monik lost three games this way out of 500+ total.
