“Enable tweaks” not staying checked

I love this plugin and it has worked perfectly on every site so far. Lately though it’s not been behaving. I checked “Enable tweaks” on the homepage and it won’t “hold” for some reason. Every now and then the page goes back to constrained width, headers, title, etc. When I go back to edit the page, “Enable tweaks” in unchecked. It’s pretty random so I haven’t been able to pinpoint what’s causing the issue. Thought I’d list it here to see if anyone else is experiencing this or has some insights.

Thanks!
