Problem: Two records with similar primary key names should exist but only one appears in the cache.
Solution: Check to see whether your datasource is configured as a case insensitive repository. Unwired Platform requires that the datasource be case insensitive. This may require that you change at least one primary key name so they use different characters. Without these changes the first primary key data is overwritten by the second, and this issue will be propagated to client databases when the user synchronizes.
