Clion debugger doesn't show values inside stl containers

Hi, tried searching for the answer everywhere, but can't seem to find anyone with the same problem. 

Debugging a http server on MacOs, it's been like that for a while… 3-4 months ago I definitely didn't have this issue. Most often the problem is with unordered_map/set, some other containers show “invalid value” instead of their contents also. Please help !
