Re-balancing of Syfe Reits + on 24 Sept 2021

I received an email abt the re-balancing of my Syfe Reits + account.

Today i did a computation to see what is running behind and discover so illogical rebalancing action been performed thus resulting to loss.

​

For example, for ARA, they purchased 148.69 units on 24 Sept to bump up the weightage which they target at 2.11%. but on 5 Oct they sold 11.67 units when the market is down? Why do that? Can't they just purchase 148.69 - 11.67 on 24 Sept itself? Rather then buy more and then decided to sell.
