Using OL and UL in content blocks not showing as formatted lists

[Tim Wade]

When I add custom blocks and add Lists either with UL or OL and LI items...

the text displays however no formatting that looks like a list.

It seems to be removed via css... or am I missing something super obvious?

I checked default templates without any customizations, and it does the same there.

Any advice on how to get the list formatting to return for my content blocks?

very specifically
my test site URL
https://www.megairon.com/

on the home page, the "SELL WITH CLASSIFIEDS" block near the middle of the page... the entire content is defined as an Ordered List <ol> ... but no list formatting is taking place as expected.
