Answer 1

These required fields are hidden in form so validation fails;
<div class="form-group col-lg-10" id="student" style="display: none;">
<input type="text" class="form-control" name="institute" placeholder="Institute Name" value="<?php echo set_value('institute');?>">
<span class="text-danger"><?php echo form_error('institute'); ?></span>
</div>
<div class="form-group col-lg-10" id="professional" style="display: none;">
<input type="text" class="form-control" name="company" placeholder="Company Name" value="<?php echo set_value('company');?>">
<span class="text-danger"><?php echo form_error('company'); ?></span>
</div>
but validations are in controller
$this->form_validation->set_rules('institute','Institute Name','trim|required');
$this->form_validation->set_rules('company','Company Name','trim|required');
remove the validation if not needed. :)
