Key words changed and new added after posting

This is getting ridiculous!   I spend a lot of time...literally hours composing appropriate key words to my uploads, but they are disregarded and new irrelevant auto-generated ones replace the carefully selected keywords.

This happens ALL THE TIME!!!

Can someone please explain WHY I can't use MY keywords that make sense?  This is very frustrating and unprofessional. 

Why do I have to go back and redo EVERY SINGLE photo I upload after the fact and redo all the keywords.

Auto-generated keywords are for lazy people and should not even be a function of your service.   I am constantly having to re-enter again and again the SAME keywords...only to have them regenerated.

This is causing me a TON of extra work for no reason but to accommodate people who are too lazy to take the time to enter them in themselves.

I have complained about this before...with no response or attempt to correct this horrible feature.  PLEASE FIX THIS!!!
