Couponcode does noet show on iPad

Hi,

I am using responsive couponpress version 6.6.3.
I am using coupon button type click to copy.
When I look at my site on PC or iPhone, I see the couponcode. (see attachment coupon code not missing).
When I look on my iPad however, there is no couponcode. (see attachments coupon code missing 1 and 2). You do see the button which appears when you have chosen coupon type = offer.
Can you help?

Regards,

Astrid
