How do I fix headers and spacing in ASAP?

Hi,

We are about to launch our KB and we were checking how it is looking like in ASAP. We noticed that the headers do not look as they should: header 2 looks like header 3 and vice versa. I had a look with dev tools and it says h2 (has smaller font than h3 (which is also bold) - that does not make sense.

These are the headers in the KB - header 3 at the top and header 2 below.

These are the same headers as they can be seen in ASAP: deader 3 at the top and header 2 below.

h3 in dev tools

h2 in dev tools

How do I fix this? As these headers are misbehaving, so are the spacing between them and paragraphs. The usual spacing that works in the support website disappears in the ASAP widget, so I had to add breaks as a workaround.

Thanks for any help in advance!
