Not an answer to your question, but for me it seems that you have Winbox open to internet?????
If so, you are at high risk of being hacked. (older RouterOS has a big bug)
Use VPN to access winbox, then you do not need to block anyone.
If VPN can not be used, follow these steps.
1. Use another port than default.
2. Use port knocking. This prevents someone from seeing open ports.
3. Use a long and good password.
4. Use access list to prevent any random internet from accessing your router.
5. Log everything. (See my signature for example.)
6. Upgrade firmware to latest stable release
7. ++++
Your access list does block some IP to not access Winbox. In step 4, you should block all, only allow valid IP.
