I have run into an issue where I create a view with the filters in the image below (the list is a modern list in SPO converted over from 13' to SPO by share gate). The issue is that I continue to see all of my list items previous to 2017 which date back to 2013. this seems like a Microsoft bug. Has anyone else experienced this and is there a workaround?
I have done a test in my SharePoint online list, when i filter with created is greater than a time, the items are displayed fine in the list.
Try to filter only with created is greater than 1/1/2017 and compare whether the issue exists.
Try to do a test in another list and compare whether the issue exists.
