Checklist flash not working properly with UNDO button

[rcflyinghokie]

If you UNDO in the Checklist MFD, which moves the checklist back a step, the flash in the VC does not follow the new checklist position and remains on the item it was indicating.

In 2d, if you undo with flash, both the switch before UNDO and the one UNDO moves the checklist to get highlighted simultaneously.
