Hi @mr-dang,
OK, I have reproduced your issue. But with different steps I got different result. So I will state both here.
The steps I took that reproduced your issue:
1. Click on File > Media > Browse, a "1.png" image is added unter Media.
2. Insert an image control, then immediately change under Advanced the CalculateOriginalDimensions property to true and the width and height accordingly.
3. Set the Image property to "1".
4. The dot shows.

The steps that will show the image correctly:
1. Click on File > Media > Browse, a "1.png" image is added unter Media.
2. Insert an image control, then immediately change the Image property to "1". And the image shows correctly.
3. Then under Advanced the CalculateOriginalDimensions property to true and the width and height accordingly. The image is still there.

Other steps that will show the image correctly:
1. Insert an Image control, then I click on the Image tab > Image dropdown > Add an image file.

2. Then in Advanced, changed the CalculateOriginalDimensions property to true and the width and height accordingly.
3. After this, my .png image shows correctly like this:

So would you please try with the 2nd and 3rd method to add your image and its dimensions?
Regards,
Mona
