Using Studio One 5.5.2.86528 on Win10.

The undo button stopped working in one of my projects. Other projects work fine. It just says "Undo  Edit Multiple Parameters" but it doesn't do anything when I click it. Very frustrating.

Disabling and Enabling the "Enable Undo" option under advanced settings didn't help either. This has made working on this project a major pain. Shouldn't be happening in a professional DAW. Any ideas how to fix it or export everything into a new project while keeping all inserts, settings and automations?
