The first one only provides 1 expansion and the other one 2. I counted the expansions on my live server and they match just fine. Did you maybe research a technology from Space Age Mars recently? There is currently a bug, that these can also unlock colony expansions for further ages.
I checked your research log, you did indeed research one way later, that includes 3 colony expansions, but that was before Titan released. But this is most likely still the cause for the issue.
This means this issue is already known
