Hi, @givap
It is because you just select the Footer for your homepage: https://prnt.sc/10oy5an (Custom Theme Options) while you still do not select the Footer in Theme Options: https://prnt.sc/10oy6d4
And the Meta box option is still being enabled. You should turn off this mode then select again the Footer in Theme Options, then all settings in Theme Options will be applied for your whole site and the inner pages. Please click Edit page: https://prnt.sc/10oy7ct > Scroll down then turn it off: https://prnt.sc/10oy80b
I also do this for you and now the footer is showing on every page.
Please check again then let me know
Regards,
Yame
