Spellchecking with CheckMate PTBR

Hi,
I would appreciate input from Language Tool/CheckMate specialists.
I have been trying to run a spellchecker for PTBR in CheckMate, and I only get results from the grammar check rules in Language Tool and no results for spelling errors.
For Spanish and Russian the spellchecker works fine.
Any suggestion?

Thanks

Are you using a locally running LT server? If so, what does it print on the command line when you run the check? I’m looking for something like this:
