Nodes not showing on the workspace

As seen in the image below, Nodes are not showing. If I delete the Archi-lab Mandrill package and restart Revit, the problem gets resolved. But, my script has nodes from that package. It’s only happening in Revit 2021. Any suggestions??

Make sure you are using the most up to date version of Mandrill, and that Revit has all updated applied as well. If the problem persists check your notifications for add-in conflicts; if any are listed remove all Revit add-ins and see if the problem persists.
