How to hide image “captions”

[Wkstr]

Here is an image I uploaded using markdown syntax, no caption

But after previewing on the webpage, image-20220728203041331 is displayed at the bottom of the picture

I want to know how to modify the source code to delete or hide image-20220728203041331, or where is there a switch
Maybe the problem is not here, and I implore the developer to explain the possible reasons.Thanks!

I'm an idiot, just change the square brackets in the md file
