The version I’m using is 2025 R2 Build 25.200.0248 and the issue is that the Modern UI Files and the rest of that functionality is missing from the Customization Project Editor even tho the build version I’m using is the latest and inside the other instance I’m having for the Acumatica tutorials is working absolutely fine. Here’s a screenshot of a fresh customization inside the problematic instance I’m using

even after the creation of a screen with marked creation of “Modern UI Files”, the link in the navigation menu doesn’t appear

also forgot to mention that the Modern UI is currently active
