Issue with Column Limit in Pro Plan: Failed to Create New Column Error

Hey guys, why am i getting a "Failed to create new column. You have reached the limit for action columns in this table" when i just have 45 columns on my table? I thought it's 75 or something? I'm on a PRO plan just in case there is a difference or something changed. here is the link to the table: https://app.clay.com/workspaces/302827/tables/t_xUdeX34b6Pae/views/gv_W8PDmBSMZC5d
