Wrong predict at very simple sentences

[SemihDurmaz54]

Sometimes VADER gives wrong results at very long sentences and i get it but for a very short and simple sentence like:
"Very clean, no problem" should be working correct.
Here is the result for this sentence:
{'neg': 0.577, 'neu': 0.106, 'pos': 0.317, 'compound': -0.3504}
While the sentence is highly positive, VADER says it's negative

Hello @SemihDurmaz54 , today I tested this sentence and I actually got an accurate result:

Very clean, no problem------------------------------------------- {'neg': 0.0, 'neu': 0.128, 'pos': 0.872, 'compound': 0.6997}

Looks like they updated the algorithm.
