The options for radio button and checkbox fields were not appearing properly in my registration form. The first option showed up to the right of the other options and had a greater space after it than the other options did.
FIX:
1) Go to DTRegister Component
2) Go to Configuration
3) Go to General tab
4) Set "Form Field Styling" to "Styled by DTRegister Script"
5) Save
I hope this helps someone else as I struggled with this for a long time.
As stated in the other thread for this... the problem was your template. There is a styling being applied to a massive string of variables, which is not good CSS in our opinion.... and it is affecting the form values. Never actually seen it look this way on any other site other than yours. Anyway, you switch it to be styled by DT Register and the issue goes away because it bypasses your site template.
In most cases, it is best to allow the fields to be styled by your template so it is uniform with other forms on your site. You can fix your template CSS... or just use the DT Register styling script. That option is there to use as needed. Thanks
