Font changing size when adding bullet points

When I add bullet points or numbering, the font size changes. This is how the code appears when I change the format to text. Can anyone help please?

1. All the restaurants have to serve the same type of cuisine. In this experiment, we chose French. Mainly because French restaurants hold the most Michelin stars and we would be able to try 1,2 and 3 stars in London without too much difficulty. (Saying that though, finding a three star restaurant with availability at lunch time is proving a challenge!
2. We have to have the set menu. This will keep the experience as consistent as possible.
