£10,000 monthly cap for fee-free Fronted payments and GBIT

Hello Curve Community

Would someone know how moving a transaction (previously made as Fronted) with Go-Back-In-Time affects the £10,000 monthly fee-free limit?
If I made a £2,000 fronted transaction (with an underlying creditcard) in January, what happens when I move it to February (using GBIT) to another underlying credit card?: will this reduce my February £10,000 limit, or will it not on the basis that it primarily used the January quota?

Thank you so much for your help
Have a great day!
