Like and thanks buttons

I have searched the forum but not found this problems. 
I have activated the Like button (not keen on the FAcebook lookalike, but deal with that later) the like button is for Topics only, I understand that and can live with it. 

I have activated the Thanks button, not the reputation button,  the Thanks is only showing on a few post not all of them or in every topic.  The ones that do have a Thanks button, once clicked you can no longer thank any other member in the topic the Buttons disappear. 

What have I done wrong this time?  will I need to do coding? 

the thanks button only shows in topics that you have started .. you can also only thank one person per topic

like on here its user most of the time to thnk the person that has solved your issue

Thank you, not quite what I was meaning,  but I searched through Google and it threw me back into this forum   and I found exactly what I was looking for,
