According to my knowledge, Freedom partners are licensed to use music from Epidemic Sounds, but today i saw in the audio tab of my video that I am using a copyrighted music!
Please publish your video as hidden, so you can only watch the video if you have the link. I had the same issue a while ago. Once you get the strike, you should contact Freedom to ask if they can remove the claim, if the music you use is really partnered with Freedom. If it is, the claim will be removed a few days later.
