Trending @Accenture; Tag issue in project allocation need advice

On Monday I got one project call and accepted that one. After 1 day when I asked them about my project allocation status they told

"we have forwarded your case to our PMO but it didn't go thru due to some tagging issues"

Not able to understand what type of problem is this 🥲

I asked him need to do anything from my side he said NO

Any one face same can explain me what type of issues is this?
