Double applet icons in Linux Mint

[Boyfinn]

Environment

Linux Mint 21.3

Bug description

Ulauncher applet icon shows up twice in the applet tray. I've gone to the applet settings panel and made sure Ulauncher doesn't appear there twice. (In fact, it doesn't appear there at all).

Steps to reproduce:

1. Install Ulauncher system package from apt
2. Enable "Launch at login" from settings
3. After a couple reboots, a second Ulauncher applet appears in the applet tray. Both function the same when clicking. Exiting one exits both.
   For some reason this never occurs to me after a single reboot after installing the package. It often takes a couple reboots before the second icon appears.

OS: Linux Mint 21.3 x86_64
Kernel: 6.5.0-1020-oem
Desktop: Cinnamon 6.0.4
Ulauncher: V5.15.6
Ext.API: V2.0.0
