I have been using Sigil for half a year now, and these strange things keep happening. Therefore, I decided to take the pictures of them and posted them here, hoping someone more experienced can answer for me why these are happening.
The first problem is illustrated in pic2 (please see the red circles I created).
After I pasted the document into a new Sigil file, I went to the Source Code View and found the strange things I marked in the red circles. What are these, and are they needed?
The second problem is illustrated in pic3.
After I left and entered the Source Code View several times, I discovered that this area was getting bigger with nothing showing up! What's going on?
The third problem is illustrated in pic4 and pic5.
I discovered that each time I inserted a picture, something like what I circled in red would appear before the picture document. I then found out that it did was to "normalize" the properties of the picture file. So again, is something like this normal?
