Strange Copy Master Detail Behavior

I'm having trouble with the copy master api on mobile.

Copy Master Detail API is below. Works great on desktop. But on mobile, it makes 2 copies when the URL button is pushed (I tried 'pushing the button lighter and quicker to test if i was accidentally hitting it twice. I am not).

What is strange, is if I remove the numbers of the Report Links to copy, it works just fine on mobile. Makes only one copy. See below.

var text CopyMasterDetail = URLRoot() & "db/" & Dbid() & "?a=API_CopyMasterDetail&destrid=0&sourcerid=" & ToText([Record ID#])

& "&apptoken=xxxxxxxxxxxxxxxxxxxxxxxxxx"

& "&copyfid=116"

& "&relfids=75,73,191,189,193,429"; // IF I DELETE THESE NUMBERS IT WORKS FINE

var text ReturntoFieldHome = URLRoot() & "db/bpu98ejpu?a=showpage&pageid=101";

var text LandingURL = $ReturntoFieldHome;

$CopyMasterDetail

& "&rdr=" & URLEncode($LandingURL)
