Visibility Parameter - moves dynamic block?

[BMATT]

Ok, so I am making an awesome dynamic window block.  I am using all my constraints, the window stretches beautifully - however, I am trying to add a couple of different "muntin" patterns to the windows that will nicely stretch along with the window - for the most part, I can accomplish this just fine.

However, when I add my visibility parameter to the block (to toggle between muntin patterns, or none at all) - thats when thing go wrong.

When I test my block, I can select the size I want from my look up toggle, then when I go into the visibility toggle and change it from one pattern to another (or again, none at all) the whole window block moves to the left about 2".  What is up with that?  I have tried erasing the visibility parameter and reinstating...and it just keeps happening.

Any thoughts?

Thanks,
