I have several stores in my Shopify Partners account.
I have a custom app built and I've setup admin links for my order page to 'more actions' on several stores, they look like this: 

Issue: On one of the stores for some reason these buttons are not displayed on order view page, even though it seems that everything is the same. It does show on other pages other than the order view, for example on the order list view: 

Please advise what can be the reason it's not shown specifically on the order view page?
