Problem: new kernels not showing up in boot menu

I can install new kernels, and I see them in /boot/efi/{PARITION_UUID}, but they don't show up in the systemd-boot menu.

Data

Normally, Fedora shows the 3 latest kernels (plus a recovery kernel) in the boot menu. I only see up to 6.11.6 in the systemd-boot menu. On the /boot partition, I see much newer kernel versions (both labeled fc40 and fc41)

Systemd-boot

I started with other distros on this disk before I settled on Fedora. Since I was happy with systemd-boot and its automatic discovery of boot entries, I chose to use systemd-boot when I installed Fedora. I know that Grub is the default bootloader and manager for Fedora, but I have systemd-boot. It's an option in the installer.

Major OS upgrades and rolling back the rollback

Last weekend I upgraded from Fedora 40 KDE Spin to Fedora 41. On the next Monday morning, screensharing in Edge Browser had stopped working, so I rolled back to a Fedora 40 snapshot with BTRFS Assistant. This turned out to be an issue in the latest Edge version, not in the underlying OS, so I rolled back the rollback and went to the Monday evening snapshot, then upgraded my packages.

Ever since, I'm not seeing new Kernels in the systemd-boot menu. Any idea how I can fix this, short of a fresh install of Fedora 41 KDE?
