[R-sig-ME] x axis wrong with effects to plot an interaction based on lme4

[caroleperso]

Hi
I have the following results based on a glmer Analysis : 

Random effects:
 Groups Name        Variance Std.Dev.
 N      (Intercept) 1.1885   1.0902  
 STIM   (Intercept) 0.2347   0.4844  
Number of obs: 650, groups:  N, 65; STIM, 10

Fixed effects:
            Estimate Std. Error z value Pr(>|z|)    
(Intercept)  0.02678    0.22648   0.118   0.9059    
GDSc        -0.45738    0.15979  -2.862   0.0042 ** 
MMSEc        0.07461    0.04863   1.534   0.1250    
int          0.69647    0.13217   5.270 1.37e-07 ***
MMSEc:int    0.04365    0.02043   2.137   0.0326 *  

I have plot the interaction with the effect package

plot(allEffects(fear), multiline=TRUE)

however the x-axis is false limited to a max value of 2 while the max value is 3.84.
I have tried many things but that do not work at all. I also find curious that the values are integer while all are decimals.
any help?
many thanks
carole
