Shifting of editboxes starting on second element

Hello,

Help us please with the following problem:
The first field everywhere looks good, but the second field label is shifted to the right, and the rest underlying editboxes are shifted below.
It is reproducing with the following forms: Existing Users Login, Reset Forgotten Password, New Users Registration. The problem doesn’t depend on using CSS template.

Screenshots of the the problem: https://www.dropbox.com/sh/e46vww8imkgagse/Yzn1c-pf0c#/
