Hello Joey,
There's a pending version for this app since Saturday. I tested a few issues reported in this topic, including the one you said, and I couldn't reproduce. The fix provided here is the right one for IPS 4.5. You can do it yourself if you have FTP access and if you want to test it out before IPS review new version.
Regarding values, they're the same; I didn't change it and the renewal remains $15:
