only the ones at the front take effect when using multiple powertags

[Morganwan90]

When I use two powertags, only the first one near the front will take effect.

If the second powertag is placed at the end of the sentence after the first one, it will not generate a new attribute.
Placing a new powertag in front of the first one, although the second one will take effect, the original first one will not function as intended (such as deleting attributes).
