Unable to List All Items in Dataset

I have a field BRAND that represents multiple car brands and now I’m having an issue with displaying this field.

It works with no issue when the field sorting is not applied. However, I want the field to be sorted by A-Z but when the sorting is applied to the dataset, it only shows the first five brands of the items(as shown below).

Why am I encountering this issue, can anyone help me?
