"Export a PDF" button doesnt work when extension is installed

I am using the starter.api extension as an example, all the extension does is a PIHandshake, set the extension name to ADBE:Starter, and set PluginImportReplaceAndRegister/PluginInit to true.

when this extension is active, and Acrobat is in the "new Acrobat" UI, the Export a PDF button looks clickable, but when i bring the mouse cursor to it, it doesnt bring out the submenu. When it is in the old Acrobat UI, the "Export To" button does expand to the submenus. this happens in 2024.003.20112. Has anyone else run into this issue? do i have to enable anything special in the Plugin Initialization for it to behave in the "new Acrobat" ui?
