Quick Edit Option is not visible, though the Setting option is Enabled

Hi Team,

We are using a Share Point List, it is observed that the Quick Edit option is not visible regardless of the selection at

1. Advanced Settings->

2. View-> 

I compared my List configuration with the List which has Quick Edit and all the options match.

I understand that Configuring a new list would be of an alternative but I would not prefer it, as the existing List has data.

Please suggest.
