Thin white line appearing between some sections.

Site URL: https://oncueregina.ca/whats-on/season/making-it-right-walking-in-the-right-way

I am getting a thin white line that appears below (and sometimes above depending on how I fiddle with it) the Ticketing section of at least one of our webpages. Any thoughts on this? The webpage I'm noticing it on is https://oncueregina.ca/whats-on/season/making-it-right-walking-in-the-right-way (Password: TestTestTest)

I have tried 

section#introduction {
    background-color: black;
}

and

.Index-page--has-image {
    background-color: black !important; 
}

Both of which were suggested on the forum before. Is there a site design colour setting I could use to fix it? I have not been able to find it so far and I'm trying to avoid custom code unless needed.

Hi.

It looks fine here. Can you take a screenshot?
