Nick here from Shopify. Great question!
From Shopify's perspective, we are limited in how we would be able to help directly with this since it is a third party developed theme. The language of the code is different from what the Shopify themes team would be familiar with. Because of this, your best bet would be to reach out to the theme developer directly about it as they would know their theme best. The theme developer for Sunrise is Rawsterne and you can reach them directly on their website here.
Also, hopefully, someone with more knowledge than I see this and can help also, but I thought I'd help point you in the right direction of the theme developer in the meantime.
All the best, Nick
