That did it! Thank you, Anh!
I renamed the version to 4.17.3.1 on my local copy from your Github version. Should I expect for this fix to be in the next repository update you make? I haven't used Github enough to know if I will need to manually switch back to the repository version when it's available.
For what it's worth, I also ran the update for AIO that came out today. That did not fix the Beaver Themer Integrator Shortcode. Just so you know.
Thank you!
