Sheet.Isplaceholder gone?

Hi guys, I have downloaded archilab into a new installation of revit 2020 and I can’t see to find that node to filter out place holder sheets. Does anyone have any info on that, was this added some how under another name or as built in functionality of Dynamo 2.3.0

This node is in the archilab package. You may have multiple versions installed preventing the correct version from loading. Check the ! at the top of your Dynamo window for more info.

Can you please help me sort this out? Which version of archilab do I need? image

Not sure what happened, but I removed it, then installed the 2020.23.13 version and its working !
thank you
