Lines are listed in Drawing Objects list but not showing on chart

[cre8able]

I making an indicator that draws lines at swing highs. If it finds equal highs, the lines are drawn in a different color to show that there is more than 1 high at that point

I find a swing high
I check to see if it is the first swing high at that price
If it is, I look back to see if there is an equal high that isn't a swing high. If I find one, I draw a line from the equal high to the swing high. Then start a new line at that price that is a different color

if it's not the first swing high at that level, I draw a line from the last swing high to the current one, then start a new line at that price that is a different color

In the top image you can see that there are 2 lines that are in the Drawing Object list that didn't draw on the chart. But when I click on a line to bring up the Drawing Object list, then close the box, the lines show up. That's the bottom image

My code is below
What am I doing wrong?

        protected override void OnBarUpdate()
        {
            if (CurrentBar < 2)    return;

            }

            if (swingHighs.Count > 0)                                                //    GO THRU LIST AND DRAW ANY OPEN SWING HIGH LINES

Hello cre8able,

Thank you for your post.

It's possible that if no data was coming in, the chart may not have refreshed until you clicked on the line.

Could you please create a simple reduced test script without the excess logic just draws a line every 10 bars (or something similar) and see if this reproduces the issue?

I look forward to assisting further.

[cre8able]

thanks Gaby
I found a different way to program it and it works fine now
