Kaggle competition list filters not working

Hello, when running:

kaggle competitions list -s titanic

I get:

['ref deadline category reward teamCount userHasEntered \n',
'------- ------------------- --------------- --------- --------- -------------- \n',
'titanic 2030-01-01 00:00:00 Getting Started Knowledge 18134 True \n']

but when running:

kaggle competitions list -s titanic --category gettingStarted

I get an empty list, this is just an example but it is happening systematically with all my searches, I think this is a bug on the code.

SortBy also not working.

thanks in advance,

Siria
