Sharepoint Online ID filter

Hi 

I have a SharePoint Online list (with more than 5000 records) which is having a strange issue:  When i try to filter by ID column (which is automatically created by default by SharePoint) it appear a strange value which is not a number, as it is shown in the image.

I want to delete this record but, if I filter by this there are no records returned.

I tried exporting the list to Excel but also with no luck. 

I also created a Power app for finding this record, but nothing.

Any Idea how this value is appearing and how can i delete it?
