[M.A.I.N.]

Where is the internal click coming from? An audio track? You need to choose your tempo first before you start doing stuff and stick to the grid. With 6.7 they introduced tick based audio so you could change the tempo of the whole track, even the audio files since they are based on the ticks of the grid. Set your grid mode to bars|beats and see if your click sticks to the grid, if it is off then this is your problem.
