Not list "PROBLEMS"

I know how to suppress warning from being treated as errors with build_flags=-Werror…
but they still display in yellow in the problems list (and I have a lot of the same problem showing up which I can ignore).

How can I not have them appear in the PROBLEM list?

bitwise operation between different enumeration types '<unnamed enum>' and '<unnamed enum>' is deprecated [-Wdeprecated-enum-enum-conversion]

THANKS!
