Bot not combining potion stacks

So, the server I’m playing (Silkroad Royale, Ares server sro-r.com) has the potion stack limit 250, and you can buy 250 potions from the NPC at a time. However, the bot only buys potions in stacks of 50 and does not combine them. So if I set the bot to buy 250 potions it will buy 5x50 instead of 1x250 and the potions take 5 slots in my inventory. It combines arrows and all other items fine, so I’m not sure why it’s not combining/buying the potions in bigger stacks. Bot version 23.4.6

Sounds like the stack in the client is not set correctly.
