Bug FTB Retro SSP 1.2.5 - Inventory Tweaks not working properly

[SnowWolf263]

I am unsure of where I should post this. But inventory tweaks doesn't sort in any inventory except the players inventory and i have to press the sort button to do so (R). the buttons in the top right of the inventory doesn't even pop up. Does anyone know whats up?

It's 1.2.5, crossmod support was very patchy back then, though I thought sorting worked with Iron Chests at least.

it worked once and then the buttons disappeared, after that middle click didn't work. I don't want to mess with it to much since i don't want to corrupt the modpack. all i have done is refresh the config for inv tweaks
