Why is "kubejs forge" mod no longer updating here even though it's updated on curseforge?

Not sure if this is the right place to get help from a member of the Aternos team but,

I am trying to follow a certain modpacks list of mods by adding them manually (because there are a few extra mods I want to personally include on top of that), however, one of the mods required is "kubejs-forge-1605.3.18-build.152". While the mod is supported on aternos, for some reason, it doesn't show any of the version updates new than April 23 2021. . . even though there are ALOT of newer ones for the same version uploaded on the curseforge page it's linked with.

Why is the list (for 1.16.5 atleast) not updating even though the curseforge page is?


If there is a more proper place to direct this question directly at the aternos team, please redirect me to there as I fear this is a topic more to do with their side than anything else. I'm just hoping it's some glitch but I fear it's something worse or akin to a decision on their part where they might potentially be causing this issue intentionally due to "technical reasons/motives". I don't know for sure though and that's why I am here.

I don't think I can progress with my server or their services until this gets resolved. . . and if it doesn't, I might need to just abandon the platform entirely to make this work sadly. . . so I'm kinda desperate here.
