The loss of Portlandia doesn't surprise me. I bought mine from Roseland after seeing that Heirloom's Portlandia plants were never viable.
Pickering didn't sell any own-root roses until last year, so all of your Pickering roses are grafted. They should grow well in your zone. Sunrise, in particular, should be at least 6 feet tall after four years. Maybe it was stunted by the container. It's not a rose I would ever grow in a container. It's huge.
The cold winter may be the reason for your small leaves and blooms. The roses may be taking longer than usual to awake from dormancy.
It's also possible that you overfertilized. Roses exhibiting any signs of stress should not be fertilized. Overfertilization could cause cane striations and various other problems.
I'm in a completely different location from you, but that kind of damage on my roses would make me suspect underwatering (they might need more water than they're getting) and damage from underground creatures. I have gophers, and before I started planting in gopher-proof cages, the nibbling at the roots would create one-cane rose bushes, stunted growth, and worse. Voles could be an even bigger problem because they cause damage above and below the ground. They eat the roots and gnaw at the above-ground portion of plants.
