Yes,
The “repair and refuel” binding mentioned in @DJW3592 's post can cause the system. I had the issue with unlimited fuel once and I think that was the solution for me. I had it bound to one of my switches on my bravo throttles. So check for that option in Controls first.
If that doesn’t work, I would try backing up a copy of the “fs-base-ui-pages” folder and deleting it from the OneStore. This folder contains the Assistance Options along with a number of other menu options. You must remove the entire folder to trigger MSFS to redownload it when the sim is starting up. If it doesn’t work you can restore the folder you backed up.
