Myself and several other Android users who have the latest IBM Verse update installed (10.0.1.0 201811071627) and in the past week have found that the calendar has stopped syncing and entries are missing.
Going into Tools and replacing the data for Mail and Calendar fixes the issue, but the next day it happens again and the process has to be repeated.
It seems shortly after I posted this IBM released an update the the Android IBM Verse client - 10.0.1.1 201811151612 which appears to have fixed the issue.
