Wire clamp in Carlon new work box

I am wiring my garage for overhead lighting. Ceiling joists exposed- will be sheetrocking. I've got a couple wire junction boxes- plastic Carlon new work boxes from HD- that will feed power to a number of florescent fixtures. I broke out clamps on these two boxes- and other locations in the house where it is too late to swap out boxes- and passed 12/2 wires though the holes. 2 questions.
1. Should I fill holes with fire block caulk or duct seal?
2. How many wires are allowed to pass through these holes? In some locations I did put two 12/2s through the hole with clamp broke off.
I am certain I am within wirefill specs for these boxes.

The clamps are for one cable.

IMO the boxes should be replaced.

Where boxes cannot be replaced is using fire block caulk acceptable?

Technically no. If the boxes cannot be replaced then you have no choice.

If they are the single gang blue boxes, that is not a clamp, it is a seal. You break them out to install the cable. They will break out easily, where the clamps do not.
