Two things - customers are not assigned to a particular store. So every customer is able to login into every store. The second case, I suppose that products are not limited to store. Even if created first or second, you need to limit them from the Stores tab on the product.

How will I able to add a store manager for a specific store?

It's quite simple. First of all, when you edit your customer, you need to select the store in which this users should be added. Instead of Not a staff, you need to select a particular store. Then in the "Customer Roles" tab, you need to mark the "Staff" role. Then you need to be sure that ACL is properly configured, Staff role should have marked:
- Access admin area
- Admin area. Manage Categories,
- Admin area. Manage Files,
- Admin area. Manage Manufacturers,
- Admin area. Manage Orders,
- Admin area. Manage Products,
- Admin area. Manage Reports,
- Admin area. Manage Return Requests,
- Admin area. Manage Shipments.

Then please ensure that you have unchecked "Ignore limit store rules" and "Ignore ACL" in Catalog settings -> Performance. Finally, each product, category, the manufacturer has to be assigned to a particular store. If you assign it to both stores or you won't assign them, both managers will see those products.

Hi Patryk

I just installed the one-click install on Digital Ocean and the Limit Per Store slider seems to no longer be present.  Has it been removed in the latest version (and need to manually change the appsetting.json) file or moved elsewhere?  I am not a developer but trying to evaluate Grandnode and the multi-store was important to test.    

can you please explain these words "Then redirect your domain to your store"
