Cross-Reference sheet limit



I am having issues adding cross-references to my sheet. I have a total of 51 cross refence links on my sheet yet I am unable to add anymore. I have read that the max number per sheet is 100.

I have scanned through each reference and have found that after crossref47 it jumps to crossref96 in the next cell. I have tried to manually change the cross-ref name to the next in the series but smartsheet tells me that that number is already in use on the sheet. I have looked through the whole sheet no cells have crossref48-95.

How can I fix this error? I have tried to create a new sheet and start again but the exact same happens after crossref47. Is there a way I can filter through cross refences on the sheet to see where they are being used?

Thank you for your help.
