If optional, second value's CSS goes wrongly

If I put radiobutton field and many text values there and then set it optional. Then when i try to edit a page of that content type, I noticed that the second value's (right below N/A value) text after radiobutton is on next line, instead of inline. CSS is showing this:

<div id="edit-field-religion-value-<p>Antroposofia-wrapper" class="form-item">
<label class="option">
<input id="edit-field-religion-value-<p>Antroposofia" class="form-radio" type="radio" value="<p>Antroposofia" name="field_religion[value]"/>
</label>
<p style="">Antroposofia </p>
</div>

When it should be like this (like the others are):

<div id="edit-field-religion-value--wrapper" class="form-item">
<label class="option">
<input id="edit-field-religion-value-" class="form-radio" type="radio" checked="checked" value="" name="field_religion[value]"/>
Ei mikään
</label>
</div>

So, some reason p-tag goes outside of label-tag...
