STM32C0116-DK default project shows configuration warnings

[MWebj]

I installed Cube 1.18.1 and selected STM32C0116-DK (STM32C0xx eval board) and created a test project. But when I open the .ioc file to check hw config I can see that there are warning signs on ADC1, TMR1, TMR3 and USART1. 
I disable SPI1 and USART2 but it doesn't remove USART2 in Pinout view, so I reset pins there. Warning signs on TMR1 and TMR3 disappear.
Still warning on USART1 : "PB6 mapped with GPIO output", but PB6 is not in the GPIO Settings for USART1. PB6 is used by LED on eval board.

How do I get rid of the warning?

Also, ADC1 complains about conflict with DEBUG: Serial Wire. The odd thing is DEBUG is using PA13 and PA14, and I can't see that ADC1 is using any of those pins.
Why is there no "Disable" for ADC1 ?

What are the warning signs ?   yellow or red ?

...just show a pic. :)

Yellow

[AScha.3]

Something like this ?

Thats no problem, its only a info : no more all functions or pins available, because already used.

Because every pin has many possible functions, you always will get this yellow info, as soon as you use a pin for a certain function,  on all other peripherals then maybe this warning, that other peripherals cannot be used on this pin any more - its "occupied".
