Weird behavior while Suppress “Bookmarks” button in SAPUI5, Fiori

Some times ago i've successfully suppressed the "Save as Tile" button that exists in the Standard Fiori App, MM_PO_APV:

// Standard application buttons (Remove Forward)
   this.setHeaderFooterOptions({
  oPositiveAction:{
  sI18nBtnTxt: that.resourceBundle.getText("XBUT_APPROVE"),
  onBtnPressed: jQuery.proxy(that.handleApprove, that)
   },
  oNegativeAction:{
  sI18nBtnTxt: that.resourceBundle.getText("XBUT_REJECT"),
  onBtnPressed: jQuery.proxy(that.handleReject, that)
   },
  onBack: jQuery.proxy(function(){
   //Check if a navigation to master is the previous entry in the history
   var sDir = sap.ui.core.routing.History.getInstance().getDirection(this.oRouter.getURL("master"));
   if(sDir ==="Backwards"){
  window.history.go(-1);
   }else{
   //we came from somewhere else - create the master view
   this.oRouter.navTo("master");
   }
   },this),
   // Remove the 'Save as Tile' button
  bSuppressBookmarkButton :true
   });

But they had updated the SAPUI5 version, I think the lastest, and it comes with a problem. The button is appearing, but with a weird behavior, as you can see:

All my code remains the same, and as I've seen on documentation API, it remains the same too.

Could you help me on how to resolve this?
