change in appearance

Hi!

Two days ago I updated a plugin (don’t know if it has anything to do with that) and afterward, the front page of the theme changed suddenly.

When I open the customizer to change and correct it, under settings I can see it appears fine the way it was before, however, that’s not what it shows when I save. Also, when I try to change to something else completely, it won’t show that.

Please see my site here.

If you have any thoughts as for why this might be happening, please let me know!

Thanks!
