Cannot open subdirectories in directory tree after updating

[Yumac]

I had been using version 3.37.2 with no problems. Yesterday, FileZilla said there was an update, so I downloaded it and installed it. Version 3.37.3. I then opened it and tried to open a subdirectory on the server so I could download some files to my computer. I tried to open public_html. It didn't open to show the contents. Instead it started downloading the entire subdirectory. I tried opening a few others and the same thing--cannot open them.

When I went to file a bug, I was shown a message that the software was out of date. How can the application not have downloaded the current update? The app gave me 3.37.3 and said I was up-to-date.

I downloaded the adware-free version for 3.37.4 from the Other Options download page (https://filezilla-project.org/download.php?show_all=1) and tried to use it. The same thing happens. After both updates, no subdirectories will open. Clicking twice on a folder downloads the entire subdirectory automatically. I tried right click on a folder and I was shown a list but it has Download selected and there is no Open selection so I can't get to the contents from the list.

Please check the directory doubleclick action you have configured on the file lists page in the settings dialog.

The context menu item to enter a directory is "Enter directory".

setting is set to Enter Directory but doesn't work

I have checked the settings for double-click action on a directory and it is already set to "Enter directory". See attachment. What else might be preventing it from opening a directory?
