PDF Reader truncating at 256?

[Bobbins]

Good Afternoon,

I am currently trying to use the following tool:
https://gallery.alteryx.com/#!app/PDF-Input--Text-and-Image-/5be5ec8d0462d71ffce6deaa

And it works, ish. If i connect a browse, I can see the full text field, however if i connect any other tool to it (like a select tool or text to column) it truncates the data going to it at 256.

There is no fields to adjust but I dont get how the browse sees the full field and yet any other tool has it it truncated.

What am I missing?

Apologies
