UDT Copy (BUG?)

When copying tags inside a UDT folder from itself or other UDTs, the tags loose their value source, data type and Source.

Please see Image
Copying the controlcorealarms1 folder and pasting it inside dualpumpalarm UDT, creates a folder with controlcorealarms2 with the tags showing up in the parent folder. If copied one folder at a time then it looses the properties.

Is this a known bug?
