What is the easiest way to solve this problem please
We had run into this same problem not so long ago. The Holes Series was constrained by a set of ejector pins which were in the assembly, in the way of the hole path. These were the "Multiple component instances" inhibiting the Hole Series.
If running into this issue, remove any parts which may be taking up space in, or mated with the holes you use to start the Hole Series with. In our case, this solved the problem.
