Maybe this was covered in other posts… when I highlight a block of text in order to create a slide for it, all is fine. However, if I begin to type something more in the same paragraph as that block, all of a sudden the slide is updated with the text from the entire paragraph. This seems to be a recent bug that wasn't there before. I am using what I think is the latest version (39.1.6).
In addition, I used to be able to change the format of a slide and then tell Logos to update all slides using that style. That no longer works. It just ignores the "Apply this style to all slides". Again, this worked in previous versions. Now it doesn't. I concur with others that some functions are regressing in these releases.
