Problem selecting toolchain/exporting

I have an SX1276 tranceiver chip that I need to connect to a LPCXpresso55S16 board to send and receive data. When going to the SX1276Lib to export it, I selected the LPCXpresso55S69 board as the one used because it was the closest available option to the one I am using but when clicking on the “Select toolchain” menu all the options including MCUXpressoIDE which I need are greyed out and I can’t click on any of them. The same happens when I tried to export the SX1276PingPong example.

What could be causing this issue? Thanks for your answers
