List boxes created with PDF Architect don't work with Adobe Reader IOS

First time post so hope I get it right. So in PDF Architect I've created a list box with a group of numbers. The box works fine if I use a desktop app to open and fill in the form.

However with Adobe reader on iOS it doesn't update the values. You get to see the drop down list. tick an option but the number does not update. Screen shot attached to help make sense of this.

Even if you select a number and then move to the next field the values aren't updating. It is an Adobe or form error?

Hi,

please send an example PDF to support(at)pdfforge.org and we will have a look at it, I will also create a form here with PDF Architect and do some tests. Which version of PDF Architect do you have installed?

Best regards,

Robin
