Sometimes no input parameters in the saved report

 

For same code, sometimes there are not input parameters shown in the saved report after back testing. But sometimes the saved report is fine after back testing.

In case that the report is saved and hasn't parameters in the report, html file, I always couldn't save a report with parameters no matter how many times to save reports by MT4 terminal.

Although I met the issue many times, I couldn't find the pattern and still don't know how to fix.

I searched on the internet and found a video which I can't open. May I ask for suggestion or support?  Thanks.

 

No friend has the same issue?  

How did you work around?
