i use the 5.4.3. version on mac OS big sur; i have the same issue but only with the height gauges altitude graphs. All titles, other gauges are shown in the export en in the edit mode the graphs work perfectly. I tried several different height gauges, but all with the same result; the background of the gauge is shown, but the graph itself not. I tried other colours and backgrounds, but still no success. the video comprises approx. 50 clips and photos where all individual clips were synced with g-metrix costing 8 hours of work.
I did a test with a short movie using the start and end clip of the movie where it doesn't work. Then it perfectly shows the whole graph in both start and end clips.
how can i resolve this?
