Issue with Product Variation

Hello,

i am developing an e-shop with Enfold shop theme.
So far all good.
I realized in the process that the variable products don’t change image when i am setting it in the variation.
The only way i can change the variation is if i haven’t set on the product a featured image.
Searching for an answer i checked google developer console and i found that i had warnings:
[DOM] Found 6 elements with non-unique id #_ajax_nonce: (More info: https://goo.gl/9p2vKq)
[DOM] Found 3 elements with non-unique id #avia-save-nonce: (More info: https://goo.gl/9p2vKq)
[DOM] Found 2 elements with non-unique id #current-page-selector-1: (More info: https://goo.gl/9p2vKq)
[DOM] Found 2 elements with non-unique id #woocommerce_meta_nonce: (More info: https://goo.gl/9p2vKq)
[DOM] Found 2 elements with non-unique id #product_length: (More info: https://goo.gl/9p2vKq)

Can you help me fix with these issues?
If you need access please say so and i will send you an account to make the changes.

Thank you.
