Why is the solver running twice?

I'm running a standard static study using the automatic solver (No h or p-adaptive involved), so why are most of the tasks running twice?

Solving contact constraints is one of the tasks running twice. This task takes a long time to complete so I'm concerned that my simulations are taking twice as long as necessary.


This only happens with a certain series of models, each copied from the previous model.

Perhaps some form of modelling issue has occured somewhere down the line.

Or is there a reasonable explanation for this?
