Song falsely flagged as "[using] another artist's stem or sample"

Finally got around to uploading music to Distrokid, only to receive this email a few hours later:

"We're told by stores that there's something wonky with your release, which is preventing it from going live.

Please see the issue(s) below:

Additional detail: Track(s) 3 appears to contain elements of another artist’s music (Africa Love Dub by Linval Thompson). Stores do not allow you to use another artist’s stem or sample without their permission."

Aside from both being in the key of B minor there is nothing similar between these two songs. Email didn't contain any additional information. What the hell do I do now?
