assuming you installed them in the order electric, toxin, heat. The first electric mixed with acrid's innate toxin damage which made it corrosive, this is still considered a single element however (does not apply to one mixed element limit) so the second toxin you applied mixed with heat making gas, as mentioned in this page, gas has a chance to deal AOE toxin damage. Unless something else is happening this will likely answer your question, try checking the stats of your weapon in the Arsenal and make certain of which elements are actually active.
