Sinatra Theme Button and Image Justification

@sintatrateam – Often A button or image that is center justified in the container reverts to default left justified after publishing. We recently noticed all “Subscribe to Our Newsletter” image on the bottom of the blog posts moved to left justified. (1) Is there a global action to fix that? (2) Have you seen this before?

The same thing happens with buttons in the block editor sometimes. We publish with them center justified and they revert to left. Sometimes the block editor preview won’t reflect the chosen position of left, center or right either.

Any help would be greatly appreciated!
