#903 trxGui doesn't move multiple items but it does move 1 item

[Astara]

If I select 1 item, right click, I have the option to "Set data location...", a popup asks for the new path and displays a checkbox for whether or not to move the data.

For 1 item this works as expected (location is renamed, no data is moved).

For multiple items, nothing happens (no rename (as well as"the correct behavior",
of it not being moved))
