Parts become linked. How to unlink?

Anyone found a solution to this.

It does it to me every time I glue parts on the same boundary - audio and/or midi!

To replicate start with a 4 bar part on one track then record a 1 bar midi or audio track below it.

Copy the 1 bar part to 4 bars so its the same size and on same boundary as the one above.

Glue it and its instantly deselected. Now they are horribly joined.

wwzeitler’s workaround works but its very cumbersome as I now have many parts joined across different tracks!!

Help!!
