Multi Select filed showing last selected value

Hi,

I using select control using multi select ( 4 ).

First I select for options from dropdown and save the customizer.

Then I removed all selected option one by one and save the customizer.

But it still showing all values.

But if I remove only two values and save the customizer then it’s working fine.

The problem is when I remove all selected options from drop down then it’s shows all values (Not remove them) .

Hope it clear what I want to say.

Thank you
