three strange huge volume clicking sounds ruining other audi

[Swanson]

So it's taken me ages but finally after exporting all the drums I can see that the clicking sound is coming from them. Thing is, the huge peak in sound volume is not actually really noticeable at all, but it's sooo loud that it's rendering the entire rest of the track nearly unbearable. I've exported with normalize, overload protection and none, same every time. Heres two pics where I've moved the drum tracks that seem aligned with the clicks above the audio entire songs waveform.

What's going on here an how can I get rid of this to get a normal volume track exported?

Finally figured it out, it's to do with vertical change in frequency automation like picture, simply changed the lines to gradients a voila!

 

Problem was every point like this:
