-ivregress- not reporting first stage output

[Lorien Nair]

Hello Statalisters,

I am running an IV wherein I run the following code:

foreach var in transa transb transc transd{
  ivregress 2sls `var' `demog' `political' (endogvar = instrument), clust(region) first

}

However when the first stage output is reported the corelation between instrument and endogenous variable are not reported. Instead only the other exogenous variables are reported. This is not an issue when I remove all control variables.

ivregress 2sls transa (endogvar = instrument), clust(region) first
