WordPress SEO by YOAST horrible

Installed version 1.2.4 and kept getting This is a Yoast Test Title even though every title was filled in correctly. After many saves and refreshes worked again. Went to 1.2.5 and same problem but will not go away. Also many duplicate content issues and unable to remove the trailing slash added by YOAST SEO on my home page even though all permalinks do NOT have it. Now getting rel canonical duplicate warnings and huge number of errors. Went back to 1.2.4 and same crap. De-activated the plugin and still getting the Yoast test title so will just get rid of it. Far too many bugs in this plugin for it to be useful
