Listing Of Resources in maintenance work order's resources tab based on initial characters- Redwood

Summary:

List of resources in the resource tab of the work order are not displayed based on Initial characters typed, rather it is always a standard list that user need to scroll through always

Content (please ensure you mask any confidential information):

There are around 50 resources in a given work center. In order to add a particular resource to the work order, when the Resources LOV is clicked, all the resources are displayed. However, if the user keys in one or more initial characters , the list is not filtered. It still shows all the resources from which user need to select. Apparently the LOV seem to have recognise and remember the input, but can't filter. Is this something that's normal?
