For some reason Devonthink creates backslashes when I copy paste into markdown documents. I’ve tried to fix this in Hidden Preferences by activating and deactivating PlainTextIsMarkdown. But it does not seem to change it.
E.g. it looks like this \(John 1\:32–34 CSB17\)
while it should look like this
(John 1:32–34 CSB17)
