Edit in menu greyed out for multiple images

Hi, since upgrading to Lightroom Desktop 8.2, I can no longer send multiple images to external programs (such as Helicon Focus) using the "Edit in" menu or contextual menu. I can select a image and send to Topaz, Helicon, etc, but when I select two or more images the entire "Edit in" sub-menu is greyed out (even the browse option).

Screenshots of submenu for single and multiple selections attached.

I am using a MacBook Pro M3, with OS Sequoia 15.3.1, Lightroom v. 8.2.
