Missing menu in Customize section, by larois

Missing menu items from Appearance > Customize section. The theme am using is ‘Azera Luxury’ this only started to happen recently. I’ve tried deactivating all plugins, re-installing theme, increasing memory. Nothing has worked.

The ‘front page section’ editor within the menu isn’t in there. However, it does randomly appear during random times then disappears as soon as it is clicked.

I also believe I get the same problem with other themes. I’ve checked other posts, but nothing seems to be working.
