TLT link not working

[tripoli...@gmail.com]

Working on a spreadsheet GoogleFinance (), not working for TLT( Treasure bond ETF)

Looks like below. Note how data stops for TLT after 2/1/16. If I put IEI into TLT cell I get full data, If I put TLT into IEI I get partial data matching this post. Does anyone else have this problem? Is thered a fix? thanks
