After deleting a record from a filtered view, the UI returns to the unfiltered view.

One has a filtered view, e.g.

https://database.maths.cam.ac.uk/list.php?_view=10_IT%2F10_Physical_Computers&_pagelen=50&os_hid=Windows%3A+7&_action=search

One clicks on one of the rows, clicks "Delete" at the bottom of the page that results, and one is returned to the unfiltered view.
