Not showing ANY mp4 downloads while using log-importer

I am importing logs from an IIS server
The summary clearly shows that all the requests were downloads but when I open in Matomo under Behaviour->Downloads, all I see is There is no data for this report. I see
the pageviews and the visits but 0 downloads… And nowhere can I find any reference to the mp4 that were downloaded…

I am using Python 2.7 and Matomo 3.7.0

Here is my command line:

python import_logs.py --url=http://analytics.test ~/test/u_ex190129.log --enable-static --idsite=2

I also tried giving a list of extensions with

 --download-extensions=bin,doc,docx,exe,gz,gzip,mpg,mp3,mp4,mpeg,pdf,ppt,pptx,rar,tar,tbz,bz2,tbz,tgz,txt,wav,wma,wmv,xls,xlsx,xml,xsd,zip

Still no success

What I am doing wrong?

I am providing the summary and a piece of the log:
