Hello. I just checked my results for Nub Open 2015 on cubecomps, and my entire average is there. However, the solves are not on my profile, and I cannot find them on cubingUSA as well. Is there any way for me to contact the WCA and ask them abut this? Also, is there any way to fix it directly?

You should try to contact the WCA results team (results@worldcubeassociation.org). If your results are on cubecomps, they(re not lost anyway, and it should be easy for them to fix the problem.
