Automatic screen cycles

[embezon]

Good day!

Hardware:
Creality Ender 5 / Creality Board 4.2.7 / Marlin 2.0.7.2 / BL-Touch / Filament runout sensor.

Problem:
Printer is working fine BUT
When the printer is working there is a automatic screen change with every change a beep.
After a few screen changes it stops for a few seconds and then starts al over again.

Anyone famliar with this, and who knows how to solve this ?

Thanks in advance.
