Remove Matlab three dots

How to remove the three dots (edit: the one in the white rectangle)? I even have three three dots this time, even more annoying as usual.

They just appear randomly when I edit a loop sometimes and I cannot remove them anymore.

Edit: I want to remove this behavior, if any options allows it. Or at least, understand why it apppears.

If they are not folded code then contact Support (amd let us know what they are).

@Madmad,

Can you send some piece of code that can help me reproduce this?

[Madmad]

This is hard to reproduce as it doesn't happen all the time, which is why I asked the question as it is not consistent and I cannot understand how to avoid it. It happens sometimes when I fold/unfold a script that contains multiple lines, for example a for loop or a try/catch/end loop). Script attached is an example of what I do and where the issue is.

for i = 1:size(data,1)
    tableMerged = table(relativePosition,...
        datafileName, latitude, longitude, dateData, timeData, ...
        XXX, ...
        ); 
end

On the example of my screenshot, my code is unfolded and there is no hidden script. I cannot click on the rectangle+three dots when this bug occurs, nothing happens (compared to clicking on the rectangle when I fold a for loop for example). I use R2023a.

When this bug happens, even if I use ctrl+u it does not resolve the issue, I have to copy and paste the script that would contain the three dots in notepad++, and it would copy my entire script, and copy it back to Matlab. In Matlab I could not unfold it/see the lines inside.

I had this issue ~10 times so far this year, I will check when it happens again for bug reproduction.

I had a similar problem and it went away when I changed the matlab preferences. Turn off "enable code folding". Seems like a bug to me, but perhaps I am missing some intended purpose.
