Various properties of f:form VHs not found

Good Morning and happy new year,

I'm using your Fluid-Enterprise Plugin in version v2.0.5 and just edit a Template for TYPO3 8.7. The properties "property", "additionalAttributes", "name" and "value" of f:form.* VHs are highlighted with "This argument couldn't be found within the view helper".

Any ideas how to solve this?

Stefan
