two in-text citations when combined, one is proper and other remains with curly brackets even after updating bibliography and CWYR turned on

Hello to all  dear members.

I am working on a book chapter for SPRINGER and research papers and using endnote from about 3 years. I have searched on the web but did not found its solution. This was doing good at earlier times but then it started to show curly brackets when ‘two in-text citations  combined, one is properly formatted and other remains with curly brackets even after updating bibliography and CWYR turned on’ …and also same case of curly brackets… when a previously endnote refrance formatted file is being updated for bibliography even adding after a single new refrance or updating old.

Thus my thesis has been ruined and my 3 research papers too. I am needing your kind assitance. a single example is here.

(Dent 2000{Feder, 2006 #511)}.

Thanking in anticipation.

when i change a style to another, then endnote assigned the hyperlinks and show formats as pervious like (Dent 2000{Feder, 2006 #511)}

when converted to unformatted all refrances appears to be with hash and curley brackets for all. please have a look {Freeman, 2010 #512{Dent, 2000 #602;Dent, 2000 #602}.

you are right bro but they are appearing as first one is good in small brackets , and other is as curly brackets
