Dynamic Block Moving after editing

[GKPByDesign]

Attached are two different dynamic blocks, but they all keep moving if I open one, and save and exit. 

As an example if you change one of the lockers to have a width of 400mm, then open the bench and save, the locker reverts to a different width, help!!

Hi,

There is something wrong with Distance 1 and Distance 2 parameters:

Plus: - XY parameter is not associated with any actions.

I'd recommend you to recreate block from scratch. I would be happy to help, but I do not know for sure all the necessary conditions.
