Chrome oddity

This only happens in Chrome, latest version for Mac.

Chrome does not allow a new post to be created. As soon as we’ve written the post, the title of the post is instantly changed to a post that had been done days ago.

If we go back to older posts and attempt to change the date, to update the post to today’s date, the same thing happens, the old post’s title and content immediately fill sin the fields of the changes we just made to the old post’s date.

It’s insane.

We have dumped the cache in Chrome, going back months. Restarted. Same problem.

Can not duplicate this in Safari or Firefox.

Any suggestions?
