One way to accomplish this (that I use most of the time) is to create your first citation for whatever is on Page 1.
Now, copy that citation, by selecting it at the Person page of whoever and clicking on the "copy" button in the Citation button bar (looks like two overlapping pieces of paper).
Now, go the person and fact you want to paste it to:
If you want to cite the same page (Page 1) and detail as you already did, you will "Paste LINK" by pressing on the little down arrow next to the New button
If you want to cite Page 2, you will "Paste DUPLICATE" by pressing the little down arrow next to the New button. Now, go into the detail section and change the page number from "1" to "2". Notice that the upper right will show you have this citation linked to 1 person/fact.
It sounds like you have already "Paste LINK" to your second fact. You will have to delete that citation (use the broken chain link on the button bar) and do the above to get a "clean" citation going for page 2.
