Why subscript not showing correctly R plot

In the R code below, (seems strange to me) I'm wondering WHY the subscript in 'CT'[01] used in the legend(), ZERO doesn't show, BUT when I use 'CT'[10] ZERO correctly shows?

Here is the R code:

plot(1:10,ty="n")

## This one below, `0` doesn't show in the `CT[01]` !!!!! ##

legend("topright", legend=bquote(paste("Evidence favors A ",bold(('CT'[01]))," = ", .(round(1/Gi,3)))),
   pch = "",cex=2, bty="n", inset=c(.0,-.12))

## But this one below `0` shows correctly in the `CT[10]` Ok Ok OK ##

legend("topright", legend=bquote(paste("Evidence favors A ",bold(('CT'[10]))," = ", .(round(1/Gi,3)))),
   pch = "",cex=2, bty="n", inset=c(.0,-.12))

I think the WHY is as follows: The function bold() evaluates the expression with the subscript. Therefore it evaluates the value inside the []-brackets. Default is to interpret it as a number. This makes totally sense: Think of a subscript [i] that is evaluated in a for loop. This will do the "right" number to every plot.

Therefore the 01 will be plotted as 1 and the 10 as 10.

So if you wish to print out the 0 in front of the 1 use 'CT'[0][1] or 'CT'['01']. The first one displays two numbers 0 and 1, the second one is evaluated as character and therefore the 0 will not be omitted.
