Reading profile by range not working for some date ranges

Hey Mikko,

I'm facing the following strange problem on reading the load profile (ProfileGeneric) of a DLMS enabled meter:
Reading values by range of the profile only works within the last about 20 days, reading by range before this days do not work.
Strange is, that reading "by entry" does work even before this 20 days. Example: reading the first 96 values of the profile returns values from Semptember 2024.
Reading values by range actually only works after the 27. December 2024.

Any ideas about this problem?
