Downloaded artifacts with Google Chrome are automatically unzipped

I have two instances of Nexus Repository Manager 3.

On the first one, when I download a gunzip archive with Google Chrome, Mozilla Firefox, curl and others, the SHA1 checksum of it on Nexus is consistent with the SHA1 checksum on my computer.

With the second one, when I download a gunzip archive with Google Chrome, the SHA1 checksum of it on Nexus is inconsistent with the SHA1 checksum on my computer. With Firefox, curl and other there is no problem.

I saw that the archive is automatically unzip with Google Chrome on my second instance when I download it.

How can I have the same behavior from my first instance to my second one ?
