Data size mismatch between expected and downloaded

Hi,
I am getting weird behavior while using sentinelhub python api to download sentinel1 data.

I am getting filesize mismatch between the expected and the actual size of the downloaded data.
The file in question is - S1A_IW_GRDH_1SDV_20231226T161223_20231226T161248_051828_0642C4_9CB2.zip,
the expected size from api is 1015927181 while the actual size i keep seeing after downloading is 1785354605.
For other files everything is working fine.

Is this just an error on their side that resulted in bad metadata?

Thank you.
