Cannot Replace Routing Components

So I'm designing a plumbing system for a customer and i have completed the 3D model but I looked back over their spec sheet and realized that all the threaded elbows need to be #3000 rather than the #2000 that I did my modeling with. Now this shouldn't be a big deal as I used the standard design library provided threaded elbow, so what I've tried to do is replace component, Selected the same file but changed the configuration to #3000 and completed the replacement except now I am getting this error message that states; "Routing fittings could not be created for these segments, because the routing component files or a suitable configuration could not be found. Check the fittings." The configurations don't change any of the dimensions so it should fit fine. So I attempted to replace each fitting individually by selecting it, and changing the configuration on the top of the menu bar and then selecting okay. I do not get an error message but it does not actually replace the component...

I could manually change the names of the components in the drawings as a work around but I'd much prefer to do it correctly.

It seams like a glitch to me, The file im working on is too large to attach but if someone needs it i can send it directly to them.

Thanks in advance.
