Yes, meta template sets len of 1, where as RHS is 8 bit.

This can be fixed up during delinearization, in this case
we can know that kernel actually stores 1 byte.

The 'template says its 1 bit' is only to force an error when
someone asks to match 'socket transparent 3'.

I asked Mate to send this patch to help with future debugging,
so one can see what the mismatching values are.
