Cummins isx 2350

Have this 2350 i noticed the other day my check engine light was flashing at start up and would go away. Hooked up insite and it said about the ash level in the DPF filter. So of course i go and look at my regen history. It wasn't good at all high 4's and 5s. So i forced regen and tried to reset the dpf filter so see if i could get the ash level code to go away. It did so and hasn't been back on. On the aftertreatment history where i did my 2 force regens they were 1.9 and 1.8. So i thought hmm maybe it was just a glitch in the system and all was good. Noticed today while driving it was doing a regen and it shouldn't of been doing one as i just did the 2 force regens. Numbers are 4.1,3.3,3.0,3.7 and got 2 fault codes 3376(Incomplete regen),2764(Exhaust back pressure above normal). Now when i do a force regen with insite. The temps hit almost 900+ within 6 mins and runs for about 40-55 mins total. I'm thinking i just need to replace the DPF in here what do you guys think?

I've replaced IMAP,Doser,Delta P
When i bought the truck i had them clean the DPF that was about 5 months ago now? I Called and confirm they did this yesterday and they said it was cleaned but wasn't baked as it wasn't needed.. My guess is it now needs it....
