No 'overwrite older' option when copying

[habell]

When I'm copying from a network drive and the files are Attrib+R (read-only) I get no option with 'overwrite older'. The only options are 'Overwrite', 'Everything', 'Skip' and 'Cancel'. Why are all the other options not available when file are read-only? I noticed this since 8.51.
When the files are not read-only, the behaviour is as expected.

I'm currently on TC 8.51a (x64)

There are two separate dialogs: The one with "Overwrite older" warns when a file already exists. When the target is read only, you get a second dialog where you can choose to overwrite all "read only" files. Of course the previously chosen option to overwrite all olders will still be done BEFORE the read only check.
