Item search in Zoho invoice app

Item search in Zoho invoice app

I have been using zoho invoice for almost 2 years, and the app works great.

But recently when I try and do an estimate or invoice, every time I try to search for an item it doesn't show up.  I have to type exactly what I am looking for in order for the item to show. 

say I am looking for an item (Sink: stainless steel 50/50)  

If under search I  type 50/50, it doesn't show  

I have to type Sink: Stainless...  for it to show up.

Before the update I was able to find it just by typing 50/50

Is there anyway to fix this?
