category not found for a custom post wordpress

my websit e works perfectly excet dislaying catgeiru for custom ost

the roblem was descivred by using a winderfukl lugin :

https://wordpress.org/plugins/rewrite-rules-inspector/

to discover wher the redirection goes?

by flushing and deleleting a revious custom category the roblem was resolved
