Ionic native datepicker does not show dates

[almi13]

Hi all,

I am using ionic native datepicker since ages in my app and did not change anything the last two years. But now in a new ios-build of my app, suddenly the datepicker does not show the valid dates. I have set minDate and maxDate, the dates out of this range are light-gray as usual, but the valid ones are, to be precise, white on white background. Anyone experienced this before?

Thanks
Alex

If some does not know what I mean, two screenshots of a datepicker with valid dates between 6th of June and 12th of June (including). The valid dates are not shown. I found out, that building with target Xcode10, everything is ok, but Xcode11 causes this behaviour. Is this a bug?
