virtuemart show plus and minus buttons for article double

[Ben61]

Hi, as newbie I have created a webshop with virtuemart 3.0.12 within joomla version 3.4.8 which works fine with internet explorer, Chrome and Firefox under windows.
But when the same page is called under IOS with Safari or Chrome then the plus and minus buttons of an article are shown twice in reverse order. I use the same template as I use for the website www.ecopoll.nl to ensure unity. When i use template Protostar for virtuemart I have the same effect with the plus and minus buttons.
But when I use template Beez3 the buttons plus and minus are ok!. Unfortunately my knowledge of templates is very limited and I have no idea how to solve this issue. The webshop is reachable by webshop.ecopoll.nl

Has anyone experience with this kind of problems and who is able to help me to solve this annoying problem.

Is fine on Safari & Chrome on windows

As I will never want an over priced white box I have no way to test on Apple but it is only css

use Web Inspector in Safari to find out why too much of the background +- image is being shown

the relative css is around line 217 etc  http://webshop.ecopoll.nl/components/com_virtuemart/assets/css/vm-ltr-site.css

maybe it needs an overflow:hidden or something

I assume it is a problem on all installs as this is std. vm css (if u say it is on std. templates)

Dear GJC,
The option overflow:hidden didn't help me but you've pointed where I have to look and with some tries I could solve the issue.
Thank you very much for directing me in the right way

Kind regards
Ben
