[Question] About using 7z to compress the driver package

I repack the driverpacks of SDI with 7z,but it failed.
I think SDI cannot recognize the compressed package format.

Code:

Original Method: LZMA2:26 LZMA:20 BCJ2
repack it sometimes
Method:Delta LZMA2:25 LZMA:20 BCJ2

Is there anybody who can help me?
EDIT:7z doesn't always do this, it seems to be related to the file structure.
EDIT2:This does not seem to have anything to do with the compression method,and 7z9.20 can implement this method.
The drivepacks can be read after decompression .
The original DP_Sounds_Realtek_22035.7zDP _ Sounds _ Realtek _ 22035.7z cannot pass the second index.

 

The problem remains unresolved.

 

Thanks.
Reinstall sdi and solved the Realtek Pack. I will try to repack it.

 

The official answer is no problem. So I reinstalled SDI, and the index passed.
However, repackaging still does not pass through the index.
