Resolved NodeJS extension missing version 8

[Azurel]

Hello,

I use Version 17.5.3 Update #42 on ‪CentOS Linux 7.4.1708

In the changelog of the nodejs extension for 25.Dec 2017 I read this:
[*] Node.js 6.x was updated to version 6.12.2. Node.js 7.x was replaced with version 8.9.3.

But in folder /opt/plesk/node/ there is only 6 and 7. In selectbox of version for node.js I see only 6.9.1 and 7.4.0. NodeJS Extension is latest version 1.3.3-100. What can I do to upgrade to version 8?

I found this answer Resolved - Trying to get NodeJS 8 to work. Need some help.

Go to Extensions (left menu) -> My Extensions -> Node.js -> Go To Extension.
Here will be the list of available Node versions. Click Refresh button and you'll see version 8 available.

But that not working for version 7.4.0, maybe because there is Domains = 1? But which Domain?

EDIT: I have removed the extension and installed again.. now I have
8.9.3, 7.4.0, 6.12.2
