Access point switching channels even-though i'm configured it to to static

Question

Hi Community,
I recently changed the access point configuration to work on static channels but it still switches between channels every 15-20 minutes. Can anyone help me to clarify what's the issue? I am a beginner in these kinds of things. 
Thank you in advance

Hi @Ayush_Tripathi 
I checked in Wireshark to see how often it's happening and for how long. I found out that the access point is advertising on these other channels for only one frame; in the next frame, it returns to the normal static channel. Any ideas?

Hi @Ayush_Tripathi ,
It is still switching to a different channel even after I modified the configuration. This issue is consistent across all access points, and it tends to switch channels for a brief period.

Hi @Ayush_Tripathi,

Thank you for helping me out. Let me try that and observe if it has stopped.
It hasn't been changing for a long time. It switches for a short burst and then returns to that static channel. Not only on 5GHz channels, but it also changes to 2.4GHz channels as well.
