Unable to move limbs or any other animatable object without changing its position to an undefinable amount (Moon Animation Suite)

I’ve been trying to animate a gun for quite a while, but unfortunately Moon Animation Suite is having some technical difficulties involving moving objects. Whenever I attempt to move any moving object in particular (such as an appendage/limb), it immediately glitches out in terms of its position and it turns into (nan,nan,nan). This doesn’t occur upon rotation, only movement exclusively.

Any sort of help would be helpful. (For reference, I am using the original Moon Animation Suite, I heavily dislike the newer and much more modernized version. This is the one I’m most comfortable with. However, if this glitch is indeed fixed in the newer version, I’d greatly appreciate it if someone clarified…)
