Hi Reyna thanks for posting in the community!
I am not able to replicate this issue with the custom crop when exporting my own test document but would love to take a closer look and help you directly. Would you mind submitting a request using our contact support form and including the following information?
- The URL of the document(s) affected.
- A description of the download settings (file type document pages cropping quality etc.) that you selected for the download.
- The downloaded file and a description of what about it is incorrect or a screenshot of the issue in the exported document.
- A screenshot of the associated Javascript Console output when you download (if you wouldn't mind re-exporting your document to grab this). You can open your Javascript Console by pressing Ctrl + Shift + J (if your computer is a Windows / Linux) OR Cmd + Opt + J (if your computer is a Mac).
Thank you so much for your help!
