Link2SD Galaxy Tab 3 8.0 with KitKat topic

Hey fellow Galaxy Tab 3 peeps, I have a little problem with storage (pretty sure I'm not the first). I installed Link2SD and partitioned my 32GB card with an ext4 partition set to about 4gigs. Link2SD shows the partition, but whenever I try to set it to ext4 and reboot, it's set back to ext2 as the default when I look at the 'Recreate mount scripts' setting. I have set the default location in the program to 'External', but when I install a new app, it still goes straight to the internal storage. Is the KitKat ROM for our device not capable of seeing the ext4 partition, and if so which one is the correct one to use? There are so many cool games on the app store that require big data downloads, so I could all the space I can get. Thanks in advance.
