Search bar does not display exact slide names when menu items are disabled.

I wanted to use search bar in the player. But when i search for a word (e.g training), the result i get does not show the entire correct slide name. What i get is like this: e.g instead of Topic 1 - its showing Toic 1. Chapter 1 - is Chater 1. This is very weird.

But when i have menu enabled in player with all slide names listed, and then when i search its perfectly showing the correct slide names. I have attached my example file here.
