I need a lot more information to help here, feel free to DM me more details, but a few possibilities:
1. it's a mistake and someone put in the wrong numbers
2. it's possible you got a bonus, tax refund, or a specific month with more income? ISAs are month to month, and maybe 13% of one months income was $1700 because you had a massive bonus or tax return check that month?
3. if you make a lot of money you still pay the high payments but you cap-out before the end of the 4 years (or whatever) so if you DID pay $1700, you would probably cap-out.
If it's 2, then it should go back down next month.
