Text of my virtual column not showing in secondary header

[OlivierVanMulle]

Hello

I tried creating a virtual column with the CONCATENATE() expression, I got no errors.

However, when trying to display this in my app (primary or secondary header), no text appears.

Does anyone know why this happens?

Thanks in advance!
Olivier

Nevermind! Reloading the app seemed to fix this issue.
