[SyncEvolution] Syncing with mobical, missing phone numbers?

Hi all, first time poster, I've been using syncevolution without issues till recently with mobical.net. However just today I realized one of my contacts was missing its phone numbers. They are present on the mobical interface, a refresh-from-server does not change things. What information/debugging do I need to do (could not find a debug guide on the syncevolution site, sorry).
