Since you didn't include the weather file, I made my own based on the objects in the IDF you shared. I wasn't able to exactly replicate your results, but I do get the same sort of unexpected variability. It's just later in the year.
My first suggestion was going to be to double check that the EPW year is always 2025, and I would still do that if I were you, but I've checked my version and it's 2025 all the way down. So this feels like a bug. I'd put in an issue on the E+ repo if you have not already and make sure to point out that two variables are changing unexpectedly. This probably needs someone with EMS expertise to look at it.
