Auto subcripts / dots not working 自动填充有问题

[Zackhardtoname]

First of all I want to say thank you for creating these helpful snippets!

I followed the instructions here.
When I type bmat(3) and tab. I do get a matrix and can fill the same string over all the cells. That's it. The subscripts would remain the same.

I also tried the \cdot feature. It does not work. In fact, it deletes the cell elements to the right and down.

I have the same issue.

Do you use YouCompleteMe? it have some strange conflict with Ultisnip. Can you update the plugin and retry it?

here is my configuration:

    let g:ycm_key_list_select_completion = ['<C-n>', '<Down>']
    let g:ycm_key_list_previous_completion = ['<C-p>', '<Up>']
    let g:SuperTabDefaultCompletionType = '<C-n>'
    let g:UltiSnipsExpandTrigger="<tab>"
    let g:UltiSnipsJumpForwardTrigger="<c-l>"
    let g:UltiSnipsJumpBackwardTrigger="<c-h>"
