Dual ODTCs and HSLDriverTools errors

Hi All, while running a method controlling 2 ODTCs we get the following error during preheat: HSLDriverTools.hs(691) : array reference out of bound,

If we make it past preheat we intermittently get another error
HSLDriverTools.hs(2337) : array reference out of bound.

Has anyone ever seen this and, if so, what was the fix (if there is any)?

We are running Hamilton Driver Tools version 4.5
