Hi,
If you pass correct value in rv_result more option will not come.
If you have 6 buttons to dispaly but if you are using rv_result = 6 then it is fine.
if you have 7 buttons to display and you are giving rv_result = 6 then 2 buttons will come in more option (it will take more button also as one visible button)
Pass correct value to rv_result. it will work

Deepika.
