We can not answer these questions. (We do not have your footprint. Nor do we have the detailed specification of your project.)
All we can do is give you the general information. Read my above linked FAQ article.
I try to explain it a bit differently this time. You need to ensure that there is no soldermask where you put paste. So either make the mask cutout large enough to encompass the full copper pad -> in this case you can select the solder paste layer of the pad.
Or if you do not want the full copper pad to be free of soldermask, then you can create a special paste pad that covers only the copper area that will be free of soldermask. -> In this case do not select solder past in the copper pads. (Create a paste only pad exactly as you want it to look like)
