Validation clears filled fields

ok this validation toolkit is driving me crazy, i have already several post and no fix yet to anything :S, now i just realized that when i have validation on a form page if i leave just one field in blank after pressing submit or insert it also clears the rest of the fields example i have a form with 4 fields

Name
Adress
Category
picture

i fill up name, i leave address empty i fill category from a drop down i place a picture file and when i clic insert it gives me the correct msg that the adress field is required but it also clears all my other fields what is wrong with validation toolkit, im getting errors if i try to validate pictures width and heights i get errors if i try to validate a file extension, what can i do i **** want to return using addt and would use it if the php 5.3 wouldnt do so much harm, the forms are auto created by the data assist wizard making the insert page update search etc... i have not done any custom code to those pages just used the data assist wizzard followed the pdf on how to validate, but seems these softwares are full of bugs, and this time i have made sure i checked every video and pdf to avoid what happened to me trying to apply sha1 that i missed some videos and thought i had readed all documentation, i have lost 5 days trying just to validate with no luck

Please tech support help!!!!
