Line height issues in text over homepage hero image

Hi there, I’m using the Neve ‘Charity’ template. On the home page hero image area, I’ve changed the font to ‘large’ for the subheading (shows as 36), but line height isn’t high enough – the text wraps across 2 lines and it overlaps. For the text below that (still over hero image), I’ve set it to ‘Medium’ (shows me Font size custom = 26), and the lines don’t overlap but are too close together. The typography line height setting for all headings is 1.2, but the text over the hero image in the template is of paragraph type, not headers. Where can I change the line heights for text over that hero image, please? The site’s not live so I can’t show you unfortunately, but am hoping because I’m using a template you’ll know what/where I mean!

Thanks in advance,
Tracy
