Element settings - Selects clearable that shouln't be

### Shopware Version

Cloud

### Affected area / extension

Platform(Default)

### Actual behaviour

Some selects are clearable that require a value set and have a default value.

### Expected behaviour

You could think about which places should always have a value and add `hideClearableButton` to avoid users being able to clear these selects to null and run into validation errors.

### How to reproduce

In Shopping Experiences go into block element settings. Check every select if clear button fits or should be removed.
