The current setup for icons indicating Proposed/Approved matches are that the approved have 2 bubbles and are filled in green and a proposed match is 2 bubbles with one being filled orange and the other bring grey. When looking at this it almost seems that the proposed icon is indicating that this is a single sided match as the orange part is connected to a grey bubble, which looks like it is not connected to anything.
My recommendation would be to have the 2 bubbles for all items:
1. Approved - both bubbles filled in green
2. Proposed - both bubbles filled with orange
3. Unmatched - both bubbles filled with grey
Will not implement based on the recommendation. Please feel free to submit another approach.
