For PH1 this is normal.
As PH0 is used by default for STLink MCO then the PH0 and PH1 are not connected as SB46 and SB44 are DNF.
If you really want to use it then you have to remove SB45 and feed SB44 but in this case you will have to change the system core clock config which probably use the HSE bypass of the STLink by default.
