Menu basket styling issue

Good day,

Recently the styling of the Basket and Checkout buttons on the Menu Basket drop-down menu have changed. They never used to be like this (plain grey and square).

When I go to the Customizer and do the Menu Basket styling settings, they appear to have the colours I previously set, but they are showing grey on the website. If I change the colours for the buttons, they still remain grey on the website.

Here is a link to some screenshots:

Any way I can perhaps get this fixed?

Thank you for your time and energy.

Kind regards,
Jethro
