sword crafting

so i tried recombinating a sword basically following this guide https://www.youtube.com/watch?v=3UIogr-X1rU

i combined two swords both with shaper and elder influence

1 had 2 prefixes: fire dmg per strength and endurance charge ond melee stun

2 had 2 suffixes: +1 endurance charge and essence attack speed

i then crafted can have 3 crafted mods and 2 veiled mods on each and combined.

i ended up with 3 mods on the final item: 1 crafted veiled mod, endurance charge on melee stun and +1 endurance charge

so the result is basically an item with 1 prefix and 1 suffix. what did i do wrong? :( i expected at least 3 mods on the item? can i use my result any further? im confused now
