Material Bar Chart sometimes is not showing Label on vAxis / Vertical Axis

[Eduardo Mioto]

Hello everyone, i'm creating several chart by the same way (just differentiated by data used), and in same cases the vAxis is not filled on chart rendering.
Verifying the svg content, i were able to identify that the gridlines on chart and vertical labels were really not inserted in the properly place.

Some tries were already implemented and all of them with the same behavior, follow below some of them:

Option 1) Passing parameters without xAvis
Option 2) vAxis:{title:'Exames(min)', format:'number',minValue:0,maxValue:5,gridlines:{count:6}},
Option 3) vAxis:{format:'number',minValue:0,maxValue:5},
Option 4) vAxis:{format:'number'},

Attachment with more details.

Did you ever had this behavior using Google Chart?
Thanks.
