I've noticed a probable issue with Italy charts.

I've installed the latest version of SkyDemon Charts for Italy, Austria and Switzerland. I've noticed that Bolzano aerodrome shows two overlapping ATZs with same vertical limits (one is biscuit-shaped, the other is round; the Italian AIP only shows the biscuit-shaped ATZ).

Similarly, the nearby Trento airport appears to have no ATZ in SkyDemon, while the AIP instead shows a round ATZ.

For clarifications, You can refer to Italian AIP, ENR 6.3-5 (Padova VFR chart).

Best regards,
Filippo
