TPT19113 Data length implied by Data Schema (xxx) is not the same as record length (yyy) on TPT load

Hi TD Guru's,
I am facing an issue where I am trying to load a Fixed width file using TPT load. It has a few FILLER columns that I need to ignore and I am running into the issue as described in the subject. Could someone please help me out?
 
thsi is the error "TPT19113 Data length implied by Data Schema (23) is not the same as record length (22)". I checked the file and the length of each record is 23. I do not seem to unerstand why it complains
Here is the TPT script.
