[QUESTION] doNotRenderTheseTags parameter is working well but onlyRenderTheseTags isn't-version 3.0.0-beta.2

[EcenurOzal]

I only want to render specific tags, but when I try to use the OnlyRenderTheseTags parameter widget it acts as if I didn't put any tags, but doNotRenderTheseTags works as it should. Has anyone faced the same problem? Any suggestion?
I use it like this:
doNotRenderTheseTags: {'h1' , ....},
