Multiple options vs single option UI

On the dashboard we are building we got 2 sets of options users can pick:

Multiple options (checkboxes) enter image description here

and single options (radio buttons behavior)

enter image description here

while the look of the components is similar, their uses are different.

In usability tests, users used these components without any difficulties or once they used and understand the functionalities they didn't have any issues to use them in the other parts of the product.

But, my designer colleagues argued that the components should look different and users have to understand if its a checkbox or a radio box from the first glance.

My aim was to keep the consistency and lower the cognitive load.

Any thoughts or inputs?

Edit 1: Updated the UI, thank you @200_success for the feedback
