I took a quick look at the files involved. All 7 of them had the fonts encrypted using the IDPF method. I used Sigil to mark them as unecrypted. In PSCF9-24p086-106Helble.epub, the Figure 9 - Raindrop imp_fmt.png and Helble fig10 top p13_fmt.png 10 images showed errors. I just re-added them to the epub but they should be replaced as they are definitely corrupted.

I've attached the 7 epubs and the anthology I created from them in numerical order. One note is that many of the font files are duplicated through the epubs and I would recommend combining the font files after the merge.
