Alarm Pipeline not copying correctly

I need to copy one alarm pipeline to several gateways but I’m having some trouble with the first. I can copy the pipeline from the original to the target, it looks great in the target designer, looks fine. But alarms weren’t using it - when investigating this, I saw that the gateway webpage doesn’t see the new one. I’ve refreshed the page, new browser etc but no luck. It is in the dropdown of alarm pipelines I can choose from in the alarming tab for a tag so thats good. But its not showing up elsewhere.

Whats happening here?

Edit: Both gateways are 7.9.6
