Summoning Circles bugged in maps with more than one

I am fully specced into summoning circles on the atlas tree and I run a tablet with 1 guaranteed summoning circle and if I do a powerful map boss with that tablet the summoning circles just break and turn into a single rune on the ground that does not spawn a boss. If i remove the tablet it works fine until i get a powerful map boss + a random summoning circle then it does the same thing.
