Technical problem disrupting contributions

When hitting "Edit," "Continue,"  "Check these updates," and "Submit these updates," one is often getting this disrupting message:

21958958' is invalid

Note: if the title or name you are trying to update was added to the database only recently, it may not yet be available for updates. Please try again in a few hours.

What is going on?  You don't need to wait a few days, just backtrack and then a "moment."  This is adding unnecessary steps to the contribution process.
