The UPlay Division 2 stats (and related API made available by the Tracker Network at https://tracker.gg/) cannot register Clan XP higher than a signed long integer (2,147,483,647).
Proof: The worldwide leaderboards for all platforms have all players Clan XP converging but never exceeding 2,147,483,647: https://tracker.gg/division-2/leader.../XPClan?page=1
The stats are also visible (in a rather poor fashion) on the Ubisoft site, clicking on your profile icon > More Games > See More Stats
In addition, once a player reaches the Total Clan XP limitation, the PVE XP stat stops incrementing, even though it clearly has a higher maximum value, which is another defect. I know this because using the API front end at the Tracker Network (which uses the UPlay data as its source) I provide weekly stats for my clan mates, and since hitting the Clan XP cap, my own PVE XP has not gone up.
