I come to a similar result. Unfortunately, I have not found a marker, when to remove how many bytes. With the current knowledge, these are broken DTA files for me.
Heatpump software V3.89.5-11451 now has dta version 0x2b23. Any plans to add support?
The 1st dateset in the attached DTA file is malformed. Thus, everything else is read wrong. Also the number of datasets the file contains is not equivalent to the number in the header. If this problem still persists, please provide another DTA file.
I can confirm that I see the same problem with the attached DTA file. Debugging could take a while.
