I think the clicks might be due to a noncontinuous DATA I2S stream. So the click happens at the start of the DATA stream. If the tracks are played gapless, then the DATA stream is continuous, and there are no clicks (or the chance of a click is greatly reduced) at the start of the next track. I can occasionally get a tick (small click) at the end of the playlist. The modules are now very inexpensive, and if yours is socketed, I would just try another.
My TeraDak TDA1387*8 consistently made a sound of a record skipping a couple of grooves at the beginning of play.
