About extra Fractal Encryption

[pikaqiu.6789]

Because I completed yesterday's Daily T4(77,92,99) with the fractal god , I only got 27 Fractal Encryption. (It should be 29)
So I took a hard look at the Fractal Encryption information

I read this in wiki

(The Chaos Isles Fractal, Nightmare Fractal and the Deepstone Fractal give 1 extra Fractal Encryption on scales below 40 and 2 extra Fractal Encryption on scales higher than 40.)

(Fractals of the Mists - Guild Wars 2 Wiki (GW2W))

But it seems siren's reef will also have extra Fractal Encryption(Because today's rec has Siren's Reef（54）)

I haven't done any more testing, and I wonder if there are other places that have extra Fractal Encryption

(For example Shattered Observatory, for Molten Boss, Sunqua Peak, Twilight Oasis?)

After I finished daily, there are only 27 Fractal Encryption pieces in my inventory, and I haven't operated on selling or saving, because the number of drops is 9-10 each time, so it's impossible for me to operate two pieces separately

I really don't know what's going on in this case.
