Some variations not showing on cart and check-out page

Hello everyone!

First of all thank you for reading this, hopefully someone can help as I googled for hours and came with empty hands.

I have a single product with two variations: Cor (color) and Brilho (gloss). The variation part is regarding the gloss where there are three options (glossy, semi-glossy and matte).

On colors that have the three finishes everything is working fine, however on colors that have two or one finishes, this parameter (finish) does not show on the cart or checkout page.

I added variations differently: on colors that had the three finishes(gloss, semi and matte) I selected the color and selected “Qualquer brilho / Any gloss), it it adds the three options at the same time. On colors that had two or less finishes (gloss options) I would select the color and the finishes (on different variations). That’s the only difference I see, but I don’t understand why it would display differently.

Please see this image (on my google drive) that shows very simply what my issue is: https://drive.google.com/file/d/1Yzitajl8VI8sBmmEqzGHEOAH8YChsKoE/view?usp=sharing
