I'm not in the habit of having Alt.Binz extract / unrar my files, but I thought I'd give this a shot.
Setup:
I am on Alt.Binz 0.47.3 (in portable mode).
I do not have Autounrar active.
I only have 3 tabs visible in Alt.Binz: Download queue, PAR2, and Log.
All my nzb's import as paused, and I have to manually start them.
I don't use the search function within Alt.Binz, but there is currently only one copy of each of your examples, so I'm confident I'm grabbing the correct one.
I verified that the nzb contains a password meta tag by opening it in wordpad.
Test 1 (This is how I personally use Alt.Binz to unrar on rare occasion):
I loaded the "Sensation.2021.WEBRip.x264-ION10" nzb.
I unpaused the set and it downloaded with no trouble.
After the download completed, I switched to the par2 tab, highlighted the release (which is an obfuscated filename), right clicked, and selected "Unrar PAR2/SFV set".
The passworded set extracted with no trouble.
Test 2:
I loaded the "Sensation.2021.WEBRip.x264-ION10" nzb.
I selected the set on the Download queue tab, right clicked, and selected "Unrar"
I unpaused the set and it downloaded with no trouble.
As soon as the download completed, the passworded set automatically extracted with no trouble.
Is there a different way you are trying to have Alt.Binz extract the passworded set?
