Unhide Title Blocks

Hi all,

I am currently writing a script to batch plot sheets to DWG without the title blocks. I am using the Archilab View.HideElements / View.UnhideElements nodes to hide the title blocks. The issue I am having is that the simple script works perfectly for the hide action, but doesn’t work for the unhide node - even though it is the exact same script with just the unhide node used. Snip of unhide script attached.

Any ideas how to get this working? Or any other suggestions on a better way to hide the title blocks welcome.

Many thanks,
(Very new to Dynamo so please bear with me)
