Spell Sniper Feat, do multiple stack?

I was looking the Player’s Handbook and I saw that there are 3 different types for Spell Sniper.

Simply put, does choosing all three of them create an 8 times multiplier?

For example, say that a Lv 10 Arcane Trickster were to use the three ability score improvements he/she had to take three feats instead.

The feats taken (in no particular order) are Spell Sniper (Bard, Sorcerer, Warlock), Spell Sniper (Cleric, Druid), and Spell Sniper (Wizard).

Does each feat stack to create an 8 times multiplier for Spell Attack Range?

(EDIT: I just inputted the values on D&DBeyond, and it seem like they added the multipliers together for 6 times multiplier. Fire Bolt has a range of 720 ft and Thorn Whip has a range of 180 ft. This is increased from 120 ft and 30 ft. Is this correct on their part?)
