Passive tree bug - POE2

I respeced into a tree with two sets, then i got 89th level and put the point into a first set adjacent node and into a second set adjacent node. Somehow now the tree highlights first set nodes for me despite i have no points (first pic).

Moreover i can allocate nodes adjacent to common part of allocated nodes infinitely and then delete them spending gold, it doesnt give any stats though (second and third pics)


Have anyone run into this bug? Any solutions?

I cant be sure which nodes are actually active now, I'll try to save some gold for full respec but who knows if it helps
