"save as" behave very strange

Good evening from Japan
I have been using LibreOffice for years by now.
Currently I use 7.18 on a Windows 10 machine.

Let's say, I have a file "xyz" that is saved in one directory/folder.
Now I want to save it in a different location (different disk) where there are directories and folders of the same name.
The target folder also contains the file, but I want to overwrite it with a newer version.

E:\AA\filexyz.odt
Here I want to replace/overwrite the "filexyz.odt".
HOWEVER, the directory E:\AA\ ... has 2-3 more folders with related files.
Like: E:\AA\bb\xx\

When I try the "save as" command and indicate the directory-folder-file name ->
LibreOffice jumps to the next folder one level BELOW the one I want to save the file in.
And it keeps doing that so long, until there is no other folder any more.

LibreOffice did not do this in the past. Is there a particular reason for this behavior?
Is there a way to tell LibreOffice to save the file where I want it to be saved?

Any help would reduce unnecessary stress immensely.
Thank you.
