Hello Mishmash,
Thank you for reaching out to the QuickBooks Community. The instructions that were shared previously were for QuickBooks Online. But no worries, let's go ahead and rebuild and verify your company file. When strange behavior such as this occurs, we recommend checking for data damage. Here's how:
- Choose File, Utilities then Rebuild Data.
- Press OK to back up the file.
- Choose the location for the file and press OK.
The process for the rebuild will take place once the backup is completed. From there, run the verify tool, which can be found in this article.
Once the rebuild and verify process has been done, go back to reconciliation and see if you are able to see those check numbers in the column,
I will be awaiting your response! Please let me know if you have any other questions! Take care.
