IMG src= not loading IMAGE. Pressbooks changing < tag to &LT

I have a book that links to hundreds of images via <img src=
These links were all working fine until last night night. Any page that I edited text in last night and saved converted to <img src to &lgt and > to &lt. None of these images automatically load any more and the html tags shows up as text in the "visual’ tab. . I try to do search and replace but Pressbooks search button automatically converts &lgt to < so I can’t do this.

Note: I am assuming new release caused this problem as this problem was not occurring over a week ago when I last made changes.
