I had a regular end stoma for 6 months. And I have to tell you, most days I could recognize what was coming out from what meal it was from. Some things just don't completely break down like you may have thought it did before. I think it is okay. I've seen other people with stomas much older than mine mention the same experience.
I'm experiencing it more with my loop stoma now.
For instance, I could/can always recognize in my bag pickles, corn---of course, lettuce, and sometimes even the little bits of chicken or the ham from a chef's salad. (among other things.. this is just what I can think of off the top of my head)
You seem to be okay compared to what I experienced and what others have said they experienced. And laughed about
Just make sure you are chewing everything, a lot.
