Welcome to the forum.
Popping and clicking noises are almost always due to Latency set too fast or incorrect buffers. The program is trying to play the song quicker than the sound card can process it, so noises happen.
The more software synths and effects you add, the worse it can get.
You didn't state which program you're using (or operating system, or sound card/audio interface), but if your synth tracks have a Freeze button in them, you can click that and that will temporarily bounce the synths to audio and remove the synth from the processing chain.
You could also manually bounce the synths to audio tracks, delete the synth and Archive the MIDI tracks.
Or increase (to the Slow side) the Latency when mixing and exporting.
