Animation reset/renew

[PerFylk]

Hi. I need a guideline to remove all animations i installed on skyrim. Slal isn't working as is should be and if i take a consistenty check in Fnis, there's a mess. Have like 10000 animations but only load 151 + 53 in slal. And only general tab is in the MCM meny. Before there was a long list. Gonna uninstall all the animations that i can in nexus mod manager. But i think is required to clean in the data folder to. Please help me there!
