I'm new to this also, and had the same thing happen to me. I wrote to the stock exchange and asked who and why trading was happening after 4pm. They replied as below and provided this link:
Please note that from 4pm to 4:10pm the market is placed in Pre-CSPA. Trading stops and brokers enter, change and cancel orders in preparation for the market closing. This should help to explain why you see your shares being sold
