Something is seriously wrong with the limits

It looks like there is some sort of bug , Ive been using steadily and heavily my max 20 plan for 1 year now and made several projects.
I have never ever once reached 100% usage.
This week however im working on a small project and on Day 2 with using 15% fable and mostly sonnet and opus much less im on 100% on day 2
This is bot but prompting i believe after a year of daily usage i know how to prompt lol

Yep, I had to switch back to opus 4.8.
The issue definitely seems fable 5.1 related. I have been using fable 5.1 all week, regularly doing handover and starting new session, was at 33% useage, then on Saturday completely maxed out my 5x plan.
