Hi, i have installed PP11.2 with the relase date of sep. 20. Right after the first installation i looked into the folders of the runtime to check whats inside. Everything as normal as it was before. Then i installed the extra content, the new figures and stuff and the ZLegacy stuff as well. Now i have inside my Basic Material Folder all the materials doubled, one in the mt5 format and the other as mz5. What i have done wrong?
