Permanent Evergreen granted from spell disappearing

I was using Helm of the Gods to give my creature +3/+3 and First Strike.
Immediately after the spell resolves, the First Strike ability is dropped from my creature. It does keep the +3/+3 buff.

I have yet to try this with other spells to see if others such as Defender, Berserker, or Trample disappear as well.

This was already brought up but doesn’t seem to be getting much attention.
