Contact button not working when NOT logged in - Jobs & Experts

When a user who is NOT logged in clicks on contact me (experts) or contact (jobs) the sign up/sign in modal opens near the top of the page behind and mostly hidden by the header/menu in our theme...may not be the case with other themes but we would not want the modal so high up on the page in any case. Data CAN be entered.

It will not close by clicking on the modal or on the page in either jobs or experts...same issue in FF, IE and Chrome.

I changed the margin-top for ig-container to 300px !important (custom css) which positions the modal in the center area on the page, but...

1) shouldn't there be a cancel or close button to close the modal, or at least be able to click on the modal or screen to return to the page?
