Main Body Convergence Problem

I'm having a problem with moving ships within the main body ring. If my ships are sailing on a course and I try to move 1 or more ships within the main body then those particular ships whose position I'm shifting (within the main body) all converge together at one point within the main body ring. The only solution I've found to make adjustments within that ring is to cancel the formation's course until the particular ships I'm moving take up their new positions, the obvious drawback being that afterwards I have to set my course all over again which as you can imagine is annoying. I'm using the latest updates, HC2017.011GESEDBDUBSBB and HC2017.013GESE on top of the fully updated Matrix version which is 2015.027.
