Why any number of characters is deleted in list title

Hi, I’m trying to show the menu by using linklists api.

{%- liquid 
  // some assign there
  assign menu06 = linklists.choice_price
-%}

 

   
 

But I can’t…
It means the list tile is not correct.

the title of menu item is “- 1,000”, but the title is " - , " on web.
The numbers of character is gone…

we can’t use the number in title of menu item?
