I take it that you play on mobile, because I received a report from a CC member with a similar subject. Apparently, there are a few flaws in the mobile application of the new CDP which don't exist in the PC version.
1) The numbers shown are too high. 1207 is the number which we expect from 109 days, 880 + 109*3 = 1207. Here's what my CC mate sent me:
2) the difference is wrong. 2850 - 2840 = 10 more for one day, but the expected difference is 3. Day 108 should have had 1204 XPs.
3) The extra bonus for 110 days is missing. Instead of 1210, we'd expect it to include an extra of 880 = 2090 XPs - you'd probably have received them on PC. This is the most insecure statement because we haven't seen all the numbers, but it would only be logical from the reports here.
I have no information which number is added to the XPs on mobile - the indications are proven to be wrong to some extent.
You might have a look on the game window of the PC game to verify the expected CDP XPs.
Apparently, another FUBAR by our gentile hosts.
