This may be the key. I didn't run over thatch with a lawn mower because
I thought they were tiny enough. Now I think about this, those thatch
were likely not tiny enough. Hopefully, the OP will find your tip.

Thanks.

If you run over the thatch with a bagging lawn mower before you put it
in the compost pile you might be more successful.
