Problem running STM32Cube MCU Packages examples

[frnt]

Hello, 

I bought the P-Nucleo-WB55 kit but I'm having problems running the examples provided.

I have overwritten by mistake the demo firmware available in the P-Nucleo-68 and now I would like to download back the demo firmware again starting from the demo provided.

By looking at the documentation here:

https://www.st.com/content/ccc/resource/technical/document/user_manual/group1/85/77/14/6a/ef/77/48/3d/DM00598021/files/DM00598021.pdf/jcr:content/translations/en.DM00598021.pdf

It looks like the demo firmware for the nucleo-68 board should be the P2P_Server_ota. Right?

However, after importing the project in STM32CubeIDE and I open it's properties I get the error I reported below.

Why is the board target not selected? I took it from the STM32Cube_FW_WB_V1.2.0 repository directory.

Can someone help me solving this issue?

Thanks in advance.
