Convenient Table formatting suddenly doesn't work

One of the most convenient things that I’ve been using ChatGPT for is the formating of regression outputs from R for export and publishing into Libre Office Writer.

Now for some reason it doesn’t return the usual neat table format to me and I have no idea why. Any further instructions from me ChatGPT essentially ignores and returns the same answer back to me.

I have two screenshots (excuse the length). One as an example of how it was supposed to work and the other showing what I get now. Which I can’t use.

How I want it
(unfortunately I seem to be able to only attach one image as of now, I will try to add this in a comment)

What I get now

As you can see, for some reason I am now getting the supposed table with these dashes and lines and I don’t know why.
Any help on this would be greatly appreciated.

This is how it’s supposed to look

Note: I am using two different outputs in the two examples but it should work on both.
