lol ya 10 years is indeed a long time…
I was just having this problem and what fixed it was using the “show all used automation” key command (find the key command for it), then going to the lower right hand corner and hitting the + or - button to adjust the track height you want for all the tracks, then using the “hide all automation” shortcut. After that, for me all new tracks stayed the same height as the rest. Hope this helps
