My color themes save in Incognito only

When trying to save a theme, it doesn't show up in "My themes" in Chrome, but will only show up while in the "Incognito" mode of Chrome. The browser is up to date. (Chrome Version 92.0.4515.107 (Official Build) (64-bit))
After I had saved themes a half a dozen times, and none of them showing up, I tried opening Color in Incognito mode, and all of the themes that I had made were there, but they still do not show up when out of incognito mode. I have tried with both Google Chrome and Microsoft Edge, and get the same result. I have only tried incolgnito with Chrome.
What can I do to resolve this so that my themes show in a non-incognito browser window?
