Hi
Looks like You got 2 style files taking care of same layout and they are a little bit in the way of each other. Here some css to adjust it, but You may try disable JUB default css to see if bootstrap will fit all styling:
.jub-block .form-horizontal .controls {
float: none;
}
.jub-block button, .jub-block input, .jub-block select, .jub-block textarea, .input-prepend .add-on {
min-height: 34px;
padding-top: 0;
padding-bottom: 0;
line-height: 34px;
}
