Delete hyphens after reading pdf-files

"die Bedeutung der finan-

ziellen Interessen der Union"

I'm trying to dehyphenate the broken text to:

"die Bedeutung der finanziellen Interessen der Union"

I'm using the replace tokens operator to joines the lines and remove the '-'. It works when I try it with examples within the operator, but when I play the process the words are all still broken and nothing seems to have been replaced. Maybe someone from the community can help? Thanks in advance! Here is my process:
