High Carb Meal; Stayed In Ketosis?

I'm still testing positive for ketones in my urine and it's now been 2 days after I ate a pretty carb heavy meal. To setup the situation I had just come in from working (part time UPS) and I probably took 2/3 hours before I started making my meal for that night, which just ended up being a very meat heavy breakfast supper (sausage, pepperoni, couple of eggs).

I decided I'd let myself have an enjoyable sweet and ate 5 cinnamon rolls (~130g total). Prior to now I'd have passed them over but I recently started working as noted above with UPS, and it's around 4-8 hours a day, quite a good deal of heavy lifting, walking/running, and just generally a high impact/mobility job, so it's been great for exercise which I've done fuck all of since I started.

I'm still registering in Ketosis in regards to the ketosticks and that just doesn't make sense. I mean I'd expect I'd have a little more of a carb-leeway compared to no exercise since my muscles feel like soft butter, but not so much that I could eat 5 (extremely high GI) cinnamon rolls and get away with it. It could also be maybe I have some trace ketones in my urine and I'm actually knocked out and the sticks are just still picking up some trace?

Would like thoughts/opinions/science/magic/etc...
