I found your country in question.
Your Short 10000+ HTE for that country your only graduating ~7000. The 10000 must result from the player assist feature trying to help you. They're being hired up to fill the hole, and your getting 10K new a month. At that rate you'll catch up in ten months. However when you do, the assist will likely quit and you will be back to just the 7K a month. Your going to have to fix the real problem.
Your edu system is too weak. Your not producing the workers you need across all worker types. Whilst you still have plenty of teachers profs, you should build out more schools and unis, and try to get to at least and index of 1.2 - 1.3. I'd put heavy emphasis on that, and doing worker exchanges to speed things along.
This isn't a bug Andy will fix, it's problem you will need to solve.
