Searching in program listing may return incorrect data

[JYA]

Using Terra Themes

Go into Manage Recordings -> Schedule Recordings -> Search Words -> Titles

Search for a pattern that would normally return a result. See that a list of programs is found and various fields populated

Now press Menu, select Choose Search Phrase... Enter rubbish that will not be found. Press Enter

The screen is cleared, but for the old program description that still appear in place of the expected text :"no results found for this search"
