2007 Solidsworks to 2017 solidworks Limit dimension issue

Hello,

I'm having a issue trying to figure out how this issue occurred. The issue, opening up 2007 version solidwork drawing that has limit dimensions were the limite value was applied only the "minus(.014"" back in 2007. Opening this drawing up now in 2017 the limit is now being split equally "plus(.007)" and "minus(.007"). This is the first drawing I have come across to do this but now worried it is something that will be repeatable when going through older drawings. Any insight into how this is occurring and/or can be avoided would be greatly appreciated.

Thanks,
