clustered bar rendering labels only after branch change

[asmafa]

I'm working on a vue.js legacy project, with vite. I'm using a clustered bar.
On first rendering, the plot bar displays correctly all the labels as shown in picture below

Once i refresh the page, most labels disappear. The only way to show the labels again is by changing the branch on my project, and then returning to the previous one. The first time after the branch change the labels are displayed, and then after refresh they disappear. Solutions I tried that didn't work:

• cleaning browsing data
• restarting the server
• trying on another browser / incognito window

Is this a bug ? Or is it a problem on my side ?
