Multiple location linking issues

Intro

• Restaurant, opened 2nd location about 1.5 months ago
• Both locations are verified through the same google business account
• Both Google profiles for each location has pictures, business number, linked to my website
• Rudimentary website up (new one under construction) with embedded g-maps to both locations
• I have two business domains that I use, one is about 10 years old the other less than 1 year. I currently switched over my website from the 10 year domain to the 1 year if that's relevant.

Problem

I can't get my first and second store under the search result (could be unlinked?). For example, when I search for Subway sandwiches, every location is geolocated and grouped (location a,b,c, etc). Whenever I try to google my restaurant, let's call it Hysellio, it only shows my older store. The only way I can get both to fall under the same result (sorta like subway), is if I google "Hysellio store", which both show up as two separate entities, instead of location a, b, and c. Can anyone offer tips or point me in the right direction? I feel like I've done everything correct.
