J-BusinessDirectory - Update from 4.9.3 to 4.9.4 error

Hi 

I trying apdate from 4.9.3 to 4.9.4, but I have this error. (joomla 3.8.11)

Warning

ALTER TABLE `#__jbusinessdirectory_attributes`
  ADD INDEX `idx_status` (`status` ASC),
  ADD INDEX `idx_type` (`type` ASC),
  ADD INDEX `idx_attribute_type` (`attribute_type` ASC);

Hi,

The index update was present in a previous version.
Please create a ticket on our store and provide us joomla admin access to fix this. 

Thank you, I've already fixed it .
