Hover text do not show up if values does not exist in BOTH facet category

[happyshows]

Hover text exists in blue block

Hover text does not exist in either green or torquise block

Can't share the source data but what's happening is something like below:
Facility,ProductSubFamily,Measure,Qty
A,x,Commit,0.2
A,y,Request,0.9
A,d,Commit,0.8
A,d,Request,0.5
A,e,Commit,0.7
A,e,Request,0.3
...

        ggplot(data = dat,aes(x=Measure ,y=Quantity,fill = ProductSubFamily)) +
        geom_bar(stat = 'identity')+
        facet_grid(.~Facility,  space = "free", labeller = label_value,switch = 'both')+
        theme_bw()+
        theme(
          panel.grid.major.x = element_blank(),
          panel.border = element_blank(),
          legend.position='bottom',
          legend.title=element_blank(),
          axis.text.x=element_text(angle=30, hjust=1)
        )+
        scale_y_continuous(labels = percent)
