Comment 4 for bug 1863151

i modified it to this:

owner @{libo_user_dirs}/{,**/}lu??????????*.tmp rwk, #Temporary file used when saving

and reloaded profile with this

sudo apparmor_parser -r -T -W /etc/apparmor.d/usr.lib.libreoffice.program.soffice.bin

and the messages (of the last type) disappeared.
