Distinct Filter is not showing all items from dropdown

[oappdev]

Getting report from users that all items are not showing in the Product Name drop-down.

Example:

When selected: Category: Postage Meter Ink & Accessories → Subcategory: Ink Cartridges → Only 13 item show up from the Product Name dropdown then the 22 on the SharePoint List

Formula that I'm using

Category

Distinct('Pitney Bowes Data',Category)

Subcategory

Distinct(Filter('Pitney Bowes Data',IsBlank(Category)=true Or Category=CategoryDrp.Selected.Result),SubCategory)

Product Name

Distinct(Filter('Pitney Bowes Data',IsBlank(SubCategory)=true Or SubCategory=SubCategoryDrp.Selected.Result),ProductName)

SharePoint List total items:  128

I do have "Data row limit for non-delegable queries" set to Value: 2000

Hope i explain myself clearly.

After doing some research. The item that are being return is in "Yellow'
