Abyss- bugged

I have been unable to "complete all abyss" on several maps. I have looked all over for stray monsters. Logged in and out. Used a portal to leave, and return. No luck. just the open green hole, remains

Same. https://i.ibb.co/6RvbSrPd/abyss.png - 0 enemies left, yet 3 green dots left on one open abyss.

Fix this already, GGG. This has been an issue ever since the start of Abyss league. Why should I even put resources into juicing & running Abyss if it's a coin toss whether or not the mechanic will even work?
