ini file creation error skipped show without a title

Hello guys,

Firstly, I am not a program developer so the code is difficult for me in some way.
I tried to make a new ini for a simple epg site base on some existing ini but unfortunately I can't get it done.

The site is as below:

http://www.thvl.vn/lich-phat-song/

Channel ID: THVL1, THVL2, THVL3, THVL4

Some code I put in ini file:

**------------------------------------------------------------------------------------------------
site {url=thvl.vn|timezone=Asia/Ho_Chi_Minh|maxdays=7|cultureinfo=vi-VN|charset=UTF-8|titlematchfactor=90|episodesystem=onscreen}
*
url_index{url|http://www.thvl.vn/lich-phat-song?ngay=|urldate|&kenh=|channel|}
*
urldate.format {datestring|yyyy-MM-dd}
*
index_showsplit.scrub {multi|<div class="table">|<div class="tbl-row">|</div>|</div>}
index_start.scrub {single|<div class="time">||</div>}
index_title.scrub {single|<div class="program">||</div>}

When run the grab, I got the error: skipped show without a title at 25/05/2020 01:30:00

I think the url_index, index_showsplit and index_start is okay
What wrong or what have been missed here?

Can you please help me?
