Layout 2026 text style lists are loosing their bullets and number formatting when I re-open my Layout file

When I close any Layout file with numbered or bulleted lists and then re-open the file, the numbered and bulleted list formatting disappear, just the text remains. Is there a fix for this or a setting I need to enact? I tried inserting an external RTF file and that did not work either - when I inserted the RTF, no bullets or numbered list formatting even showed up upon insert. List formatting has always worked before for me in previous versions of Layout I’ve had installed on my same computer which is a Mac.

Thanks for any help in advance!
