iphone 7 iOS 11.1.1 assistive touch

So I can see and access ‘gestures’ at the place of voice control in assistive touch I.e the setting is default, it must display ‘voice control’ as the bottom left icon of assistive touch but it displays ‘gestures’ and I can also add gestures to the assistive touch by the customising option. So I can see 2 ‘gestures’ icons in the assistive touch and both of them work as gestures. If I add something another it looks normal as expected but ‘voice control’ is replaced with ‘gestures’ and I can add one more gesture in customisation.

I had reset all settings but the problem persists.

Anyone with the same issue?

Please help with a fix.
