So, I've tried to add a couple new things to my sidebar and ended up deleting them because there is apparently something wrong with my layout again. I can add new stuff, but when I go to edit the layout and rearrange things on the sidebar, i.e. putting them at the bottom, middle, etc., it won't work and just stays right at the very top. So I end up deleting it because that's not where I want it. If anyone knows why this is happening or how I can fix it, I will be deeply grateful.
