how was the module installed?
The things is that there seems to be 2 different versions of the module
When you download the zip from Gitlab there is a folder /modules and that's a bit outdated.
The folder /com_joomleague/components/com_joomleague/modules is more up to date.
The module in the last location doesn't have non-working tabs as it was fixed there. The problem with multiple-select is there also so will take a look.
Am not seeing the red/green radio buttons in your image so would say you installed the outdated module.
