Duplicate text rendering in Powerpoint Export.

Hey! We're demoing Convert-API's PPTX -> JPGs exporter and love the amount of fonts that are included in it. However, there are certain instances where words or strings are duplicated at the end of text areas. It's almost like it has something with wrapping text and if it needs to wrap it will duplicate. Here are some examples

Is this a known issue? Is there some way to mitigate this? I would really like to use Convert-api, but I don't think I can trust it if is adding or altering content. I can provide other resources if needed!

Thank you
