Synth triggers twice?

[Lomnan]

So when making some sort of wobble, I want to have the lfo triggered on each key press, pretty standard. However, when trying to do so, the synth/lfo seems to retrigger twice, making a quick note sound, then instantly triggering again, instead of playing as usual. When using the inbuilt keyboard on the synth, it sounds right, but when using my midi keyboard, or the piano roll, it triggers twice. Here is a clip of the sound I have, and you can hear the sound happening twice in the first second or so, then repeating as its supposed to throughout the rest of the sound.

Thanks for any help in advance.
