Esp32 MacroPad error

Using Arduino Programming Questions
1

Hi,
I am trying to make a macro pad with the DOIT ESP32 DEV KIT V1 using the BleKeyboard library for esp32

I have 10 push buttons if one of the 9 buttons are pressed then it sends a programmed keyboard shortcut but if any button if pressed while I am holding down button10 it would send a completely different shortcut

In my code when when I upload it to the esp32 I continuously get "Button 9 pressed, shortcut sent"

if anyone knows why this is happening please help, Thanks

Please check your circuit. Specially the button part. Check if the button is properly pulled up/down.

I checked my circuit and there was no problem with it I still get the message even if I disconnect the button from the esp32
