Finished installing macOS 15 but this happened

So I finished installing Sequoia on my MacBook Air early 2015 but it seems like the OCLP is at the old version. Do remind you that I DID update the OCLP to the latest 2.0.2 before updating to Sequoia during Sonoma. And now after upgrading my OCLP is at the old 1.5.0 and the Root Patch is gone. Can someone please help me? Am I cooked? Do I have to erase all my data? (If there’s a way to not erase the data do tell me because I really do not want the data to be erased.)
