Bootstrap 4 modal shifts content on left side on chrome only

[arinsinc]

I have been using fixed top navbar with two buttons (login and sign up) each triggering different modals.Both modals contain link to open another modal (login modal have link to open signup modal and vice-versa). When clicking the second modal link in any one of them, the whole content of page including navbar elements shift to left. This happens only one time, means open anyone modal and select link to other one, the page shifts, now click the link in the second modal which is opened, nothing changes.Close this modal and again do the same the page shifts.
This happens only in Chrome(latest), I've tried in firefox but everything is fine in it

Not just Chrome: I have the same issue in Safari 11.1.1 (13605.2.8)
