PowerShot G7 X Mark III Flash won't work

[Nicole456]

   I'm very much curious on why the flash won't work on the gx7 mark iii. I tried to use it on auto and SCN, it works fine . However, when I turn the flash on the M, P, TV... the flash won't work and I can't seem to find the setting for keeping the flash on . So is there any solution or setting to turn the flash on , on manual? Or the flash won't work on these settings?

You use the buttons on the back:

You can also change the settings:

There are some more settings, this is just for an example
