Yes I have, but is suppressing these regions a good idea?

No, suppressing all together is not a good idea. They just give you an idea where you have overlapping contacts. You should fix them before proceeding.

How can I fix these overlapping contact regions?

You can create multi body geometry so that contacts are not created at all.

I do have a multi-body geometry. They are essentially PCBs stacked on top of one another. But how can I avoid this error ?

Contact regions are said to be "overlapping" when the same entity is a member of more than one contact region or when multiple contact regions share the same geometry. Ansys fluent does not support overlapping contact regions. You need find the cyclic contact region and then suppress it.

the following links explains how to repair  mesh overlapping
