Error Gradient filter initialization

What is your operating system?
Win 10 Home

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
22.01.30 portable

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
I created a gradient filter for a clip and saved these settings as a Preset called ‘Blue Green’ for future use.
These are my settings:

0: gradient_radial
“shotcut:rect”: 0=406 392 857 237 1
1: “#00ff00
2: 0.784314
3: “#0050d0
4: 0.862745
10: normal

Gradient filter1
Then, when that preset is recalled, the Color property is rendered black and not displayed as defined. In the video, however, the filter is applied correctly!
Gradient filter2
I have seen this kind of behavior also with non-predefined gradient filters in projects. However, I did not succeed in doing this consciously.
This behavior makes it difficult to change the colors or the alpha value slightly.
It seems that this behavior only occurs when the alpha channel is not set to 255!

Thanks for your excellent report. Your clue about the alpha was the key to finding the problem.

This is fixed for the next release.

Thank you!
It only occurred to me at the end of the description that the alpha channel might be the reason!
