System not installed correctly

Epic games launcher does not show the installed version, as far as i can see, there is no currect version, although it works perfectly
I can install 4.20.2 or 4.21.3 preview 2.
so version lower then 4.21.3 are not shown as installed? i consider that a glitch


I’m not exactly clear on what you are seeing, but below is an example of what my launcher’s library page displays, where everything is accurate. (Please note that there is currently no 4.21.3 version available. Only 4.21.0 Preview 2). I have 3 installations of the Unreal Engine currently.

Mine looks normal too - I can install any version that I do not already have installed
