Earnings for April 2025 does not add up

[SandyMDesigns]

I sent this as an email to support. I am hoping that I will get an answer. Putting it here may help get someone to help. Here are two of my earnings in April 2025. It does not add up.

For April 3, 2025:
 Sold at $75.80 (third-party sale).
 Third-party fee: $0.15 x $75.80 = $11.37.
 Net amount: $75.80 - $11.37 = $64.43.
 Effective royalty rate: 23.7% - 5% transaction fee = 18.7%.
 Royalty calculation: $0.187 x $64.43 = $12.05.
Shouldn't I have received $12.05 instead of $8.08?

For April 2, 2025: -
Sold at $9.00 (third-party sale).
 Third-party fee: $0.15 x $9.00 = $1.35.
 Net amount: $9.00 - $1.35 = $7.65.
 Effective royalty rate: 23.7% - 5% transaction fee = 18.7%.
 Royalty calculation: $0.187 x $7.65 = $1.43.
Shouldn't I have received $1.43 instead of $1.17?

Can a moderator pass this along and help? @Scott @Mark @MarkM

My understanding is that the third party fee went up by a lot.

Also, I believe the 5% excess royalty charge is calculated as thus, working with your calculated net amount:

23.7% royalty rate: $68.43 x .237 = $16.22

5% excess royalty fee: $16.22 x .05 = $0.81

Net royalty: $16.22 - $0.81 = $15.41

If I am remembering correctly that the third-party fee went way up, that would be what brought the royalty way down. My calculations show about a 42% carveout would get you the $1.17 from $9.00, which I believe is within range. And maybe user options contributed to lowering the royalty, too?
