How do you add textViews to a Constraint Layout programmatically, connect ones start with the other's end without leaving space between?

Question

I have been trying to add textViews to my constraint layout programmatically, however, even when I set the horizontal bias to be 0, the textViews have huge gaps between one another. When I add set the horizontal bias to be 0 in the xml files however, this gap is not there. How the layout looks when the extra textViews are added

I am trying to have them like this: How the layout looks when the textViews are added via XML

My code is the following for adding a textView:

    TextView tx = new TextView(this);
    tx.setText(eventName);
    tx.setTextSize(15);
    tx.setId(View.generateViewId());
    eventsAdded.add(tx.getId());
    tx.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
    tx.setTextColor(getResources().getColor(R.color.white));
    tx.setShadowLayer(1,1,1,getResources().getColor(R.color.black));
    constraintLayout.addView(tx);

    ConstraintSet constraintSet = new ConstraintSet();
    constraintSet.connect(tx.getId(),ConstraintSet.TOP,topOf.getId(),ConstraintSet.BOTTOM);
    constraintSet.connect(tx.getId(),ConstraintSet.BOTTOM,bottomOf.getId(),ConstraintSet.TOP);
    if (index == 0) {
        constraintSet.connect(tx.getId(),ConstraintSet.LEFT,separatorBar.getId(),ConstraintSet.RIGHT);
    }else{
        constraintSet.connect(tx.getId(),ConstraintSet.LEFT,eventsAdded.get(index),ConstraintSet.RIGHT);
    }
    constraintSet.connect(tx.getId(),ConstraintSet.RIGHT,ConstraintSet.PARENT_ID,ConstraintSet.RIGHT);
    if(bias!=0){
        constraintSet.setVerticalBias(tx.getId(),(float)bias);
    }else{
        constraintSet.setVerticalBias(tx.getId(),0);
    }
    constraintSet.constrainHeight(tx.getId(),dpToPx(duration));
    constraintSet.constrainWidth(tx.getId(),dpToPx(60));
    constraintSet.setHorizontalBias(tx.getId(),(float)0);
    constraintSet.applyTo(constraintLayout);
    index++;

Edit: It appears this may be a bug with ConstraintSet not honouring Horizontal Bias input but honouring vertical Bias. I will update this when a fix comes out. (Check comments for link to issue)
