First off, changing the set from one side to the other risks work hardening the teeth and increases the chances you will break teeth off. It’s not a solution to a saw cutting to one side.
A saw will cut to one side either because the teeth on one side are longer, or somehow set more on that side. It could also be that if you filed all the teeth from one side, you have burrs on the side away from where you filed. This issue presents itself more often with small teeth. In rare cases, the hammer on the set is not square to the anvil. ( you didn’t mention if you used a set or hammer set) .
Here is what works for me.
The fix is pretty easy. Try “stoning” the sides of the teeth after you are done filing. Use a 600 grit stone, diamond plate, or even a diamond paddle and take ONE light swipe from the heel to the toe of the saw on each side to clean off the burrs. Then test the saw.
I do the single swipe every time I sharpen. I only set the teeth every few sharpenings as needed. A15 tpi saw will probably be overset by almost any saw set, even on the finest setting.
If it stills pulls to one side, take a couple more swipes on the side the cut drifted towards to reduce the set slightly and even the teeth on that side. It’s better to use light strokes and test a couple times than to use heavy strokes.
Continue until the saw kerf is centered.

Paul’s method of topping the teeth with a diamond paddle may serve to do the same thing by taking the burr off the top of the teeth.
