Probably there are some errors in the Milano FIR.PLEASE NOTE: the borders between FIR does not correspond always to the borders of ACC/FIC.
1) Milano FIR is divided in 2 FIC/ACC: Milano and Padova.
Milano FIC is further divided in 2 area: North and South of Po river, each have different FIS Freq. 124.925 in the North and 128.925 in the South. In your map the division between Milano North and South FIC is missed therefore the FIS Freq. of the South area (128.925) does not pop-up when you touch the screen in that area.
2) Milano CTA zone 1 is a single area not 2 area divided along the route M858.
3) the border between Milano ACC/FIC and Roma ACC/FIC is not correct.
4) the border between Padova ACC/FIC and Roma ACC/FIC is not correct.
5) the border between Rome ACC/FIC and Brindisi ACC/FIC is not correct.
best regards,
