Minecraft Launcher shows incorrect download value (More inside this bug)

So today I decided to try the 19w40a new 1.15 snapshot, I opened Minecraft Launcher normally and continued on, I launched Minecraft when it wasn't even downloaded yet and gives me an error, then I tried again it works but however the "Downloading" was showing the incorrect downloaded size

The default download size system was like this if I know:

Downloading <Downloaded size in MB>/<Download size in MB>

 

But it showed me the Downloaded size incorrect:
"Downloading 4445MB/64.24MB"

It shows me the downloaded size larger than the download size, the downloaded size keeps rising until the download stopped.
