It sounds to me like you are pushing the limit and maybe over the

(what exactly do you mean "center heatsink tabs broken off?" With two of

too hot.

When doubling up, according to Lutron, you break of the center heat sinks.
This derates the 1000W unit to 800 each. I am well w/in their own
specifications.

I'm not clear on why they'd want the heat sinks removed. If there are two
controls in the same box, there's more heat being generated. It seems
intuitive that you'd want MORE heat sink area, not less. Physically, was
there enough space to leave all the heat sinks intact?
