LinkedIn Problem

A long time ago, when social media was new, I set up a dummy LinkedIn account just to try it out. Later, I set up a real LinkedIn account. Now, when I try to edit my real account, it seems LinkedIn reverts to my dummy account. Shouldn’t LinkedIn be treating these two accounts as unique pages? Why should one be connected or interfere with the other? Have others experienced something like this?

Ultimately, how do I edit my real account? Any help appreciated. (Note: The names I used for these two accounts are not even similar.)

They most likely use your email or telephone number as the actual identifier for who is who. Did you use the same email for both?
