nextTrackCommand and seekForwardCommand are both called at the same time

Question

It seems that when I press "next" on control center when playing something (simulator or device), both nextTrackCommand and seekForwardCommand are getting called.

Both functions are enabled, but it doesn't make sense that both get called upon just tapping the "next" button.

Here's more of the code:

[MPRemoteCommandCenter sharedCommandCenter].playCommand.enabled = YES;
[[MPRemoteCommandCenter sharedCommandCenter].playCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    return MPRemoteCommandHandlerStatusSuccess;
}];

[[MPRemoteCommandCenter sharedCommandCenter].nextTrackCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    NSLog(@"nextTrackCommand");
    return MPRemoteCommandHandlerStatusSuccess;
}];
[MPRemoteCommandCenter sharedCommandCenter].nextTrackCommand.enabled = YES;

[[MPRemoteCommandCenter sharedCommandCenter].seekForwardCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    NSLog(@"seekForwardCommand");
    return MPRemoteCommandHandlerStatusSuccess;
}];
[MPRemoteCommandCenter sharedCommandCenter].seekForwardCommand.enabled = YES;

I've linked bellow to an example project that demonstrates this issue.
