Squarewebsites Lazy Summaries Plugin: how to remove items count from the "Load More" button?

Site URL: https://www.nimpairings.com

Hello Circle members, 

I just purchased the Squarewebsites Lazy Summaries Plugin and cannot find a way to remove items count from the Load More button. 

The plugin provider website states it is possible to remove the items count by playing with this CSS snippet but I don't understand how (I am not a coder). 

.sqs-block-summary-v2 .loadMoreButton:after {
    content: "("attr(data-items-left)")";/*attr data-items-left refreshing each time you click*/
}

Can anyone help me figure this out? Thanks a lot.

Just hide the pseudo element like this:

.sqs-block-summary-v2 .loadMoreButton:after {
	display: none;
}

Thank you so much! 

Hello again, the code snippet works when the custom CSS window is open but the items count reappear every time I reload the page. Any idea on how to fix this? 

Thank you so much!

Perfect, it works. Thanks a lot @tuanphan!
