Clear Selection

Hi;

I have a problem with hiding CLEAR SELECTED button. For example, for this product:

https://kazemibike.com/mountain-bike/flash-race-7/

This product have 2 variation and both are available: (one in out of stock)

https://kazemibike.com/mountain-bike/flash-race-7/?attribute_pa_color=blue&attribute_pa_frame-size=m-l&attribute_pa_wheel-size=26

https://kazemibike.com/mountain-bike/flash-race-7/?attribute_pa_color=orange&attribute_pa_frame-size=m-l&attribute_pa_wheel-size=27-5

User can’t switch to another variation because clear selected variation button is hidden.

Can you guys please help me here to solve this problem.

Thanks in advance.
