Difference into JSON data and presented data on typebot

I was doing my chatbot as usual using typebot, but then, I noticed that in a specific case, as shown on my images, I could have a line that is displayed on typebot editor but is not shown on the JSON, I recreated the line just in case and compared both jsons and the line is shown there.

Any Idea how could this happen and if it's a bug, or an issue that I shouldn't care too much ?
