Discrepancies in tipping screen - Square register vs Square stand (Ipad)

[squareuser28]

We have two square system (1) Square stand (Apple Ipad) (2) Square Register ( Android).
We are seeing discrepancies in tipping screen. On both we have selected "Smart Tip Amount" option.

(1) In Square Stand (Apple Ipad)
For a transaction $10 or more, the available tipping options are: No Tip, 15%, 20% or 25%.
(2) In Square Register
Tipping options are: No Tip, 10%, 15% or 20%.

Why the tip percentages are different in two different system. It is annoying and employees are making big issues with it. Is this a bug in Square register ? How can we fix in Square register ?
