"It will be a hub for training the next generation of scientists so that we continue to advance our knowledge and prevent problems in pregnancy and labour for women and families across the globe."

1. What would be the difference in meaning and grammatical structure between above and below written sentence?

"It will be a hub to train the next generation of scientists so that we continue to advance our knowledge and prevent problems in pregnancy and labour for women and families across the globe.

2. What would be the difference in meaning and grammatical structure between original and below written sentence?

"It will be a hub for training the next generation of scientists so that we shall continue to advance our knowledge and prevent problems in pregnancy and labour for women and families across the globe."

As an NES but not a teacher, I would personally not be unhappy with the original and option 1.

With option 2, I would replace "shall" with "will" or "can".

I personally would use "shall" for requirements that I place on others (in commercial contracts), whereas I would use "will" for things that I do, as part of my normal operation, to help the operation of the contract, particularly where government agencies are concerned.

In your case I would feel that "can" is probably the better option, other than omitting the word, as previously.
Hope this helps

The word "shall" belongs in legal documents and in the phrase "shall we...?"

Any other use is uncommon. You can use "will" in that sentence, but the meaning doesn't change if you do or not.

I see no reason to change the perfectly good original sentence.

You have certainly not improved upon it or clarified it.

I disagree with R21 about option 1.

I asked in question no 1 is what is wrong in the 2nd version sentence?
And how could be "will/shall" omitted?
