Wide Width being tempermental

I am having trouble with the width on the various blocks on my homepage. I’m using the free Neve theme. I want everything to be Wide Width (with some space on the sides). However, it only seems to work (or show up as wide width) on certain blocks (such as the top picture, and bottom picture & heading). I can get other blocks to temporarily be wide if I can somehow highlight it and am given the width as an editing option on the bar that appears above the block when editing. However, if I then change the width of a subsequent block, it changes the width of the previously edited block. (Hopefully that makes sense?) Changing the width on the right-hand menu doesn’t seem to change anything. Any suggestions? Thanks in advance.
