Valve symbol problem

I am a novice Diagrams 14.1 user. For some time I can not put a valve on the pipeline. The symbol is black instead of blue. The same is  for tees. Before that it worked perfect. It's annoying. Creating a new valve symbol gives nothing, the session defaults is set. I do not have any idea how to solve this problem. I will be grateful for any help

A Small suggestion, is there any issue with the connectors, exactly i don't the term in E3D these will be called as P-Points.

can you check in this aspect
