Subscription switching ends up zeroing out existing tax rate 0.0000%

[ryanr14]

When using subscriptions alongside automated rates, I've come across an issue in this ticket that an existing tax rate (added by automated rates) gets zeroed out. This only happens when you're switching your subscription. I've had a hard time replicating this on a Pressable test site, but we can easily do this on their live & staging site. If you then disable automated rates, fix the existing zeroed out rates, this never happens again.

What would be causing our automated rate service to zero out a rate just previously used to purchase a subscription? This only happens, that we can tell, when switching subscriptions.
