Trying to delete one instance of a component and all instances delete from assemblies.

Hello,

I'm running SW 2015.

I just started running into an issue today that I've never seen before and it's only happening with one part.  I have an assembly with a few pipe routes in it that use the same flange in multiple places.  I go to delete one and it deletes every one of those flanges in the assembly. 

I've tried rebooting a couple times as I know that works with some of these odd SW behaviors but no luck.

Thanks for your time.
