Hello, can a subscriber have more than one profile property? Here’s where I’m having a glitch, it might be an error in my set up?

Day 1: A user signs up for emails: enters an email welcome flow that runs over 7 days. At the start of the flow, a new profile property is added (‘In Flow’ - Welcome (email)). This allows me to create a segment of anyone who is on that flow so I can exclude them from other email campaigns for now. The profile property is removed as they exit the flow. (Profile property ‘In flow’ is removed).

Day 2: Same user signs up to SMS, enters an SMS welcome flow that runs over 3 days. Again, at the start of the flow, a new profile property is added which says that they are ‘In Flow’ - Welcome (SMS). The profile property ‘In flow’ is removed as they exit the flow.

What I’ve noticed is that when they go into the SMS welcome flow, they are being removed from the email welcome flow and I’m not sure why. I tested it out with my own email address yesterday and stopped receive the emails in the email welcome flow. I am also not in a segment I crated of anyone who should be in the email welcome flow. My custom properties also show only the SMS flow property and not the email one: 

Can you only have one property at a time? Has anyone else experienced this or might now a fix?

Thanks,

Meeta
