I Cannot change the Minecraft version  within the launcher. It just does not change to the version I have selected, so it just stays at 1.14.4, the attached video shows exactly what is happening.

I have managed to install 1.14.4 optifine and 1.7.10 forge but forge does't launch successfully. I understand why forge is not working as I need a valid 1.7.10 install first. Optifine is working perfectly fine though, albeit on 1.14.4.

No clue if this is only me or if I can fix it myself or if it requires a patch.
