multiple hosts under one alias does not work in nat rule

[jsbsmd]

I have the following issue/question.

running
2.4.4-RELEASE-p3 (amd64)
built on Wed May 15 18:53:44 EDT 2019
FreeBSD 11.2-RELEASE-p10

I manage 4 companies using secure ftp to backup their critical files to my home server. I have created aliases for each customer eg: a,b,c,d and one alias for all customers eg: "allcustomers"

I have created a nat rule to allow alias allcustomers to my ftps server.

eg:
customera =204.32.45.67
customerb = 206.203.45.4
customerc = 50.67.34.33
customerd = 27.4.222.34

allcustomers= all the above

source=allcustomers --> tcp/990 --> WAN --> redirect to LAN 192.168.0.10 tcp/990

The issue is that when I use the bundled alias for all customers, the rule does not work. It only works if I choose one company at a time. I'm trying not to create multiple rules for each company as this will get harder to manage when the clients start to grow.

The alias menu allows for multiple hosts to be under one alias name so i'm confused why this will not work.
