What did I do wrong in this send campaign?

Hi, feeling a little dumb and sad today. Can someone tell me what I did wrong in the following scenario?

I wanted to send out an event invite to two groups of people - one group who has a certain add-on suite, and one group who does not have that particular add-on suite. I used a Salesforce campaign for each group. We'll call them Add-On Suite and No Add-On for now. I wanted to use different subject lines for each group, so I split them up in a single send campaign. 

My smart list was as follows: 

Use ANY Filters (which is where I might have messed up 

1. Member of SFDC Campaign in Add-On Suite 

2. Member of SFDC Campaign in No Add-On Suite 

And then my flow was: 

1. Change program status to invited 

2. Send Email - If Member of SFDC Campaign in Add-On Suite send Add-On Suite Email 

3. Send Email - If Member of SFDC Campaign in No Add-On Suite send No Add-On Suite Email 

I thought I set this up correctly, but apparently not because everyone got both emails regardless of which SFDC campaign they were in. Why? I checked the SFDC campaign for duplicates but that's not the case, it was definitely Marketo. What did I do wrong and what can I do better next time? TY in advance Marketo Universe.
