[JENKINS-31640] TRIGGERED_BUILD_RUN_COUNT doesn't properly update when you trigger many jobs with the same name

We just upgraded and I was excited to see the new TRIGGERED_BUILD_RUN_COUNT env vars however I am seeing a bug with them

I have a MultiPlugin Job that has 1 phase and calls something like 45 jobs in that phase

These jobs are ALL the same exact jenkins job, but I pass different parameters to them

Everything goes well, but at the very end, when I look at the ENV vars, I am always short one or two in the

TRIGGERED_BUILD_RUN_COUNT and the TRIGGERED_JOB_NAMES

so those above will match, but they are short. You can see the other vars show 45 properly and the counts are right but these do not, which makes it hard for me to get the results from them since I am missing a build number. Are there any workarounds to this? I need to copy artifacts from these jobs so need these build numbers for the subjobs

I attached all my env vars printout so you can see
