I would guess that you are using FileMaker 12 and that the fields are not "owned" by the portal. As a test, enter layout mode, click the bottom area of the bottom area of the portal to select it without selecting any fields and then tap an arrow key to move the portal few pixels. Those fields that are "owned" by the portal will move when the portal moves. Those not, will not move and I expect that the two fields in question will not move with the portal.
If so, drag one field away form the portal and release the mouse button, then drag it back into the portal row and release the mouse button. then try the same test to see if it now moves with the portal. Repeat with the second field.
PS. this can happen if you place a field outside of the portal and then use the Inspector's alignment tools to pull the field into position in the portal row.
Thanks Phil, that corrected it!!! I really appreciate your quick response.
