I'm sure those more educated and I will field this better, but just wanted to share my experience. 
Hard to say if it's normal. and hope we are talking strictly achy in the muscles correct? No joint pain? For myself, my chest was sore almost 24/7 through my first blast, painful, but I saw some good growth. Hard to say only a week and half in if your are still progressing or not. Numbers were the only thing that kept me moving forward when my chest was so sore. I kept beating the log book, so I just kept doing what I was doing. I was in a caloric surplus at the time, and doing lots of soft tissue work, so it made a difference.
How much weight have you dropped since you started FT? How's the mirror looking? Lots of folks (including myself) usually recomp through their first blast, despite adding food or making adjustments. First thing that comes to my mind, if you find that you're having trouble progressing, or the soreness is really escalating, is you may need to scale back your cardio. You say LISS, but your log says HR between 130-140, which is MISS. I made this mistake myself, thinking I was doing one, when I was doing another. So that x3 a week, plus legs three times a week might be a little too much for you to recover from. At least until maybe you get a little more used to the frequency.
How are you feeling after doing cardio? Better / worse?
Last question, are you running Day 1 and Day 2 back to back?
