The ATC was referring to AIP (left) and you were flying Jepps (right).
I believe you are not the first nor the last, and suprised this hasn't been noticed by ATCs/Jepps since Jan 2019.
That’s interesting, and something they should fix, but it only applies if you were on a ALT1Q STAR. If you’d come in on a ALT1T, it’d be 4100 or above at DIXIT rather than FL75. On a direct routing to the IAF the constraints would be the ATC cleared level/altitude, restrictions on the ILS plate, what you thought was safe and sensible or a combination of these.
