Wavelab won't display Waves L4 plugin

Hi! I am running Wavelab Pro 12 and the only problem I am having is Wavelab won’t display the Waves L4 Ultramaximizer plugin, which is a go to plugin for me. I see it load it in when I initiate a plugin rescan but it is absent in the plugin menu. I have tried to load it in every category for plugins in a montage. I am on a Mac mini using latest version of Tahoe and this is the only Waves plugin that doesn’t show up. Any thoughts?

Waves L4 is working for me here in WaveLab Pro 12 with macOS Tahoe.

Sometimes I find that manually deleting the plugin-registry-arm.txt file in the WaveLab Preferences folder does a good job of making plugins show up that are having an issue.

It will force a new plugin scan which takes awhile but I find that it works better than the native way of doing a new plugin scan.
