MS 12.0.1: Custom created part cannot cut/paste, just disappears

[Who_Knew]

I created an opamp part in MS and it seems to work fine, except when I cut section A from the circuit, then try to paste it back into the circuit, it disapears.  Other opamps from the MS master database, I can cut and paste back into the circuit fine.  Or, if I select replace component from the context menu, and try to replace it with the same component, it disappears.  If I paste it near-by and make all of the connections manually, then that seems to work OK. 

Can you check the part and let me know what's wrong with it? 

Thanks.

Hello,

I found that it seems to be an issue with the zero length pins. As soon as I changed them the part behaved properly. I have reported this as it the functionalty should work regardless of the pin length.
