Can't move coordinates for fuel tanks

[UllyB 1,206]

I have a Kfir C7 which has in its LOD two 1300L and two 500L supersonic fuel tanks designed. I tried to move the center 1300L fuel tank  a little further (for symmetry reasons) but the changes made fail to implement when I run the game to see them. The same with 500L supersonics fuel tanks (I wanted to lower them a little from the wing they are attached to). Any idea why I can't do that ? I don't recall having the same problems with former aircraft LODs which had incorporated fuel tanks models in the past or am I recalling it all wrong ? Which one is it ? Thank you in advance.

You can't move them if they are part of the aircraft lod

I was afraid that was the case. Thanks. I'll try to remember that from now on.
