What can I do about BingAds errors: The Microsoft Click Id of the offline conversion is invalid

Question

While we successfully attribute most of our Bing Ads campaigns using msclkid, from time to time - about 8 per month, we receive the following (2) errors:

The Microsoft Click Id of the offline conversion is invalid
The date and time for the click ID is outside the conversion window for this goal

We are using the bingads python sdk - mostly successfully. I can't figure out why we get these errors. I can't figure out what to do about these errors. I'd like to not have them :)

I've seen this: https://learn.microsoft.com/en-us/advertising/guides/operation-error-codes?view=bingads-13

Here is an example of the payload we've sent before receiving the invalid click id error:

{'brand': 'softwareadvice.com', 'id': 10375316, 'msclkid': 'bebd46f3a93311ecb4d864525e977793', 'name': 'SA Offline Conversion', 'platform': 'bing', 'value': 125.9}  

The Microsoft Click Id of offline conversion is invalid.
Error Code - 5604 OfflineConversionMicrosoftClickIdInvalid
Error Details - None

Here is an example of the payload we've sent before receiving the date/time outside conversion window error:

{'brand': 'softwareadvice.com', 'id': 10402764, 'msclkid': '99b58b3c87b51dac2f10eaf06eb0b796', 'name': 'SA Chat Offline Conversion', 'platform': 'bing', 'value': 438.85}  

The date and time for the click ID is outside the conversion window for this goal.
Error Code - 5617 ClickIdDateTimeOutsideGoalConversionWindow
Error Details - None

I've tried to backfill these at later times: hours, days, or weeks later. I still get the errors. Any ideas for things I could try?
