Hello, Marie OKeefe
Welcome to the Microsoft Community.
Hello, thank you for your feedback on your issue here, it seems that you are experiencing an anomaly in the indexing function while working remotely.
In order to help you better, can I ask if you can use it on your current local computer, if you can use it, then if it's convenient for you to see if the indexing function is normal on your local computer, and if the problem still exists, this will check if the problem is fixed on the remote computer.
Best regards
