Issue with detaching a foundation from a column

[kari_rinne]

I can't seem to detach my foundation/retaining wall from the columns it is attached to. I added the retaining wall after I made the columns and the slabs under them but when I moved it in to its' position it dropped so that the retaining walls top is at the same level as the columns bottom. See pic attached. I am trying to move it so that they are on the "perustus" level with their height offset being -350mm. Now I can't change it because it says that they're attached to the columns but I can't detach them either. Anyone know what to do?

I also attached the model

The Retaining Wall Foundations appear to have some association with the Columns I would suggest trying the Following and Copy and Paste back to the correct Level using the reference level method.

"An attached structural foundation will be moved to the bottom of the column" when adjusting column ...

alternatively move
