1) InDesign 2023 18.5.3, Sequoia 15.2, iMac Apple M1
2) Going from Preview mode to Normal mode
3) I expect to see my Normal mode correctly
4) See attached files

These are different files over 6 months. They are not supposed to have big color frames like that. Display is OK in preview, not in normal mode.
Going back and forth between the two does not resolve this.
I have to change page and sometimes it's ok. Sometimes I have to close the file and open it back.
