[resolved] tFileInputExcel - number of columns limited?

[Anonymous]

Hello there!
I am using metadata for tFileInputExcel, where I need to process xlsx file with many columns. Namely, around 90 of them.
Everything works perfectly if I work with smaller set of columns when specifying first and last column in metadata. 
But, when I set 7 as  start column and any number greater that 61 as end column in "Add Excel File" dialog, there is a following error which prevents me from proceeding:
" Last column parameter error. Bigger than schmea columns size" - literally, with this "schmea" typo.
Does this mean that this component has a limitation to number of columns that can be processed or this is a bug?
Is there a workaround for this - I need to process ALL the columns.
Thank you.
Cheers,
