Once image markers are selected, they cannot be deselected

[alee001]

After selecting image markers, whether individual or all are selected, the deselection button cannot be pressed in the editing bar; it can only be done using the space bar.

I have no idea what OP is talking about, but there is some issue with deselection:
1.10.5 - browser - filelist - disabled 'Select none'

[alee001]

I have no idea what OP is talking about, but deselection is not available in the following case:
0. open folder with subfolders and files in Browser
1. press 'Select all files'
files are selected
2. press 'Invert selection'
subfolders are selected
'Select none' is disabled

Don't complicate a simple problem. I mean, after selecting the top left corner of the thumbnail, it cannot be canceled normally.

Pressing Edit > Select none cannot deselect thumbnail checkbox; I can only the space bar to do it.

Edit menu has nothing to do with thumbnail checkbox
you need Metadata>Check

The problem is that the Edit menu cannot deselect all checkboxes, because you have to click "Select All" each time to check and deselect them.

This is likely not a bug but an operational defect.
