Bug in Insert Time Slice?

[murav]

There should have been a set time signature in the insert Time slice parameter, but it no longer appears.
Is this some sort of problem?
Is there a workaround?

There should have been a set time signature in the insert Time slice parameter, but it no longer appears.

Please elaborate, maybe best using a couple of screenshots.

I needed to insert a measure of 3/4 time into a song that was in 4/4 time, so I looked up the method and found that it could be done with insert time slice, so I tried it, and found that there was a parameter called set timesignature, and it worked fine. However, since I found a way to do it that day, I thought I would do the work the next day, so I closed the project without recording it, and when I tried to restart the work the next day, the parameter to set the timesignature no longer appeared. .
The insert time slice box currently displays the from and to location inputs, the set to loop button, the ok button, and the cancel button.
If this is normal, what was the 3/4 time that appeared in the 4/4 time?

MuLab only supports a single time signature per composition.
Don't know where you saw an option that made you think otherwise.
That's why i asked for the screenshot(s).

That's a strange story
Screenshots are not possible, but
When it went well, there was indeed one measure break consisting of three lines among the four vertical lines lined up, and there was an input box for set time signature on the insert time slice setting screen. .
If I only get responses that make fun of me, I will continue to clarify this issue.
