tFileInputPositional - Unable to enter Pattern for complete file.

[Anonymous]

Hi, 
I am trying to create a input for a positional file which had data until the position of 886. I tried using the pattern option in the component and it does not allow me to enter the pattern for position more than 403. 
Attached are the screen shots for better understanding of what am telling. Please suggest me a solution. 
Thank you for the help and support.

These look like start positions rather than field length values. Try using the size of the fields rather than the starting positions.
