I had this problem also and the permissions were still grayed out after unlocking. After searching for answers it was clear that my external hard drive, being formatted Mac OS Extended (Journaled) should still be read-write under High Sierra. I attempted to run disk utility First Aid a number of times but received error messages. Now I seem to have solved the problem by unmounting and remounting the disk with disk utility.

I suggest you try running First Aid and then unmounting and remounting the disk.
