I can't seem tolocate selectedskymtx

I have downloaded ladybug and installed the latest version, however - I did experience various issues with it as I was not able to use most of the tools and had to follow some more steps for it to function. Nevertheless, Once I thought that it was working, I realised that I did not have several tools in the toolbar. For example, I could not find the selectedskymtx tool. I really need to use that tool and was wondering if there is any way to fix the issue quickly.
