ZingChart Labels disappeared when updating script to 2.5.2 - zingchart

Question

I updated our instance of the ZingChart script to version 2.5.2 today and doing so caused labels to disappear from a chart where they previously showed. I'm not sure if it's an issue with my JSON that just managed not to throw any errors in the previous version of ZingChart or if it's a bug with the current release.
Before:
After:
My JSON:
var maxYValue = 60;
var value1 = 40;
var value2 = 15;
var value3 = 34;
var value4 = 14;
var value5 = 20;
var zones_1 = {

Any help would be greatly appreciated. I would prefer to keep the most updated version of the script but really need those labels back.

I can't speak to exactly what the cause of your issue is between builds at the moment but our team will look into it. I did however look at your JSON and I think you can get the output you are looking for in an easier way. I have included an updated chart config below which does work on the newest build.
Full disclosure on the ZingChart team.
var maxYValue = 60;
var value1 = 40;
var value2 = 15;
var value3 = 34;
var value4 = 14;
var value5 = 20;

The issue is the offset-y attribute set for the labels & the callout tip. It needs to be removed or set to zero. The new lib code is correct because scale-x has "placement": "opposite" so it is placed above (if you remove visible:false from items you will see).
Most likely the old code was not using the correct y position of the scale thats why you had to use offset-y to correct it.
