Model selection using glmulti

Question

I am attempting to run glmulti to test all possible subsets for model selection. The following is the code that I am trying to use.

    lmer.glmulti<-function(formula, data, random="", ...){
    lmer(paste(deparse(formula),random),data=data,
       REML=FALSE,...)
    }

    glmulti <-
 glmulti(formula(lmer(transLOT~DielEnd+TidalHeight+Pier+PercentIllumination+WT+BP+Anglers+(1|Transmitter), data=RESIDENCY_FOR_R), fixed.only=TRUE),
          data=RESIDENCY_FOR_R,
          level = 1,              
          method = "h",            
          crit = "bic",            
          confsetsize = 5,       
          plotty = F, report = F,  
          fitfunc = lmer.glmulti,  
          random="+(1|Transmitter)",
          intercept=TRUE) 

A problem arises with the variable combinations. In my output, the 4th and 5th models are the same (see below) and there is a blank in-between "Pier" and "(1|Transmitter)."

If anyone could help that would be greatly appreciated.
