Unwanted sudden change in chatgpt 3.5 format

hello ,
i am currently using chat GPT 3.5 and since Saturday i have been facing an issue.
whenever chatgpt is explaining something to me and it uses numerical lists it always skips a line
for instance:
[
1
space
This is a line
2
space
This is a line

instead of (what i want)
1 this is a line (no spaces)
2 this is a line

]

i have even explained to it several times not to do it, with the correct way to do it. i also added it to the costumization option. and the problem is that it would abide with my way once and then go back to the way it is, even though i keep reinforcing that i want it my way with examples

any ideas how to fix this?
