Error on the I2 Set Current Language on Unity 2018.2 Playmaker version 1.9.0.p4

I'm having a different PlayMaker problem, but also 2018.2(.5):

Assets/I2/Localization PlayMaker/Actions/I2SetCurrentLanguage.cs(10,10): error CS0246: The type or namespace name `I2LocPlayMaker_SelectionMode' could not be found.

This is what I get when upgrading to the latest stable version. The action worked fine beforehand. If I try to manually set the SelectionMode to FsmVariable in the script, it still errors. Any tips?

Sorry, but did you update it yet? I don't see anything new in the Google Drive. I'm not in a rush, though, just wondering in case I misunderstood.
