I guess you can claim authorship on that article by clicking more options. Or you can just upload new article and I'm almost sure site will link them as I keep getting notifications from ResearchGate asking if my co-workers published these works. Not sure if not having that article linked on ReseachGate would be a problem, not like website counts citations itself as all articles on network share citations index so... see no problem in that.
But claim of authorship should solve the problem (if I understood it right).
I think your problem has to do with the fact that you created a new profile/account https://www.researchgate.net/profile/Jesam-Ujong-2 while you already had one https://www.researchgate.net/profile/Jesam-Ujong
The best thing you can do is:
-To update the first/original account
-On your profile page you can scroll down and complete/update the affiliations info etc.

-If for some reason you want to keep the second profile you can have a look here for authorship issues https://help.researchgate.net/hc/en-us/articles/14292798510993-Authorship
