Model item does not work in IOS devices

Hi Guys,

When I use Model Item, it Works very well on Android devices and browser preview,

​But the same model item does not work in IOS devices.

I used the following steps:

1 - Create a model Item

2- Select the pink color

Result in Browser preview

Result in IOS Device

Does anyone know a way to work on all devices?

Any help to fix this issue would be welcome.
