App disappears when moved to another virtual desktop

[nihil21]

Hello,
I'm having the following issue while using Parachute:

As it can be seen, when I move an app to another virtual desktop this app "disappears" from the Parachute view, but when I select the virtual desktop the app is still there: it's just "invisible" to Parachute.

OS: Manjaro Linux x86_64
Kernel: 5.12.9-1-MANJARO
DE: Plasma 5.21.5

I've just found out that this issue happens only when I start from just one virtual desktop and I add a second one. Conversely, if I start with more virtual desktops (for example, 4), everything works as expected.
