Recreate the same display, then use describe-text-properties, see
below.

See the output of the "pgrow" command above:

This shows that characters at columns 14 to 20 that come buffer
positions 34342 through 34340 are "ownFree" and should be displayed
with face=31.

It helps: the offending line seems to be the one that shows this:
- [ ] ownFree
with "ownFree" highlighted by a green underwave. Do you know what is
that underwave face? (If you don't, you could recreate the buffer in
a live session, then go to that place and type "M-x
describe-text-properties RET".)

Let's hope.
Thanks.
