Inconsistent delegates on the pool page

[chadle-git]

Describe the bug
When displaying the pool delegates some wallets are not shown as delegates.

To Reproduce
Steps to reproduce the behavior:

1. Search for a pool or go directly to my pools page https://preprod.cexplorer.io/pool/pool1jgl6h9fyy8gqt593ah638kqps4ls7c78d5p00we6qlzycdmhhvq/delegators#data
2. Scroll down and click on Delegators
3. Notice there are only 3 delegators and there should be 4

5. Now i have found a known delegate from other explorers. We can search on it or go to this stake key directly by clicking here https://preprod.cexplorer.io/stake/stake_test1uq2pnumhfrnnse0t3uwj4n0lhz58ehfhkdhr64ylptjhq9cyney6d

6. As you can see this delegate shows relegated to my pool, but doesn't show up on my pool page.
7. All of these delegates started in Epoch 67, so they should all show up on the list

Expected behavior
The pool page should show all delegates. You can see on cardanoscan.io that it does show all 4 delgates. https://preprod.cardanoscan.io/pool/923fab952421d005d0b1edf513d801857f0f63c76d02f7bb3a07c44c?tab=delegators
