Changing Select options text in Woocommerce

Hi I installed Loc Translate after reading a tutorial on how to change the “read more” text on out of stock items.. It was easy, now my out of stock items show “temporarily out of stock” which makes more sense to me. I then followed the same steps to change “select options” to “customize options” on the things I have for sale but it did not work. I tried several times, deleted cache etc. but no luck. Any advise appreciated.
