Hello, I'm a community moderator and I noticed that my updates to the community sidebar constantly get cancelled. Is this a known bug?

More details:

• I can save the new state and it displays the new state correctly, both from the community's instance and from mine, but it changes back to the previous state after some time, going from a few hours to several days.
• I'm not 100% sure but it seems like the sidebar reverts to its previous state after I make a new post in the community.
• The last time I needed to make a change was in March and it worked perfectly. I've been trying to make this one stick since October 10th.
