Trends segment is showing trends for only 3 days out of 1 week

There is a setting of 5 weeks segments and single segment is consist of 1 week. Trends stopped showing so i reset the system and trends started working fine but after few days the trends of 3 weeks (27.05.2024~03.06.2024, 03.06.2024~10.06.2024 and 10.06.2024~16.06.2024) started showing a flat line.

-I reset the system. No use

-Backup the trend file and restore it. No use

-Today (01.07.2024) i checked the segment and found that single segment of 03.06.2024~10.06.2024 was still in the 5 weeks segment even its .bck file was created. I simply re-run the process historian and the single trend file was exited from trends segments on FIFO basis.

In single segment i am unable to trends for full 7 days i can on see trends for first 3 days(27.05.2024~03.06.2024), and no trends for the next 2 weeks (03.06.2024~10.06.2024 and 10.06.2024~16.06.2024).

What can be done here ??
