HACS - Solaredge optimizers setup error

I downloaded the HACS integration for the SolarEdge optimizers info from the SolarEdge portal. Then open the Custom Repositories option and pasted the link (GitHub - ProudElm/solaredgeoptimizers: Intergration to get optimizers information from the SolarEdge portal) selected Integration from the list and clicked on Add.
Now I get the error “Repository ‘proudelm/solaredgeoptimizers’ exists in the store.” and have no idea how to continue. What does the error mean and how do I proceed from here?

I guess it means something like “already installed and available”. Was able to continue at the next line of the instructions.
