Honestly it takes time for some dogs to warm up to a new addition.
When I brought my now 2 year old boy Kylo Ren into the house my two girls who were 4 and 2 years old at the time. We're absolutely dismayed that I brought 8 week old Kylo into our lives.
Morrison my now 11 year old Lab mix has lived through many more fosters ect. And in general is super chill about dogs. Absolutely had no problem though.
I just tried to keep interactions between Kylo and the girls positive. I did the same as you and had designated areas for the puppy, so the girls could get away if they needed.
Still they weren't above showing their teeth occasionally. Or giving a warning growl. But nothing serious every happened. I never stopped the girls from growling. Because from what I have read/learned. If you try and teach the older dog that it is bad to growl at the puppy. Some dogs then skip growling/warning behavior and go straight on to biting.
It is going to take time. It us hard for family dogs to accept a new puppy. And the fact that the puppy is the cute little attention sucker. Trust me I had days I was sure the girls hated me or hated their lives with their new brother. But we just go on one foot aftee another.
When Kylo was 6 months old I took him and both girls and had them "fixed". And though they were each crated when I couldn't be there, when I was there I turned my living room into their 24 hour post operations recovery room. In other words they all felt crappy and had to put up with each other. After that week of post OP healing everything seemed to change. And the girls finally seemed to accept Kylo.
