Hello Ziaul,
The version of SP Page Builder is 5.4. The template is Helix 3 but I don't think that's involved.

I can't see a quick way of adding a screen shot but it's in the link about about the add-on editing tools section on Style. There's a screen shot about Animated headings style showing Padding and Margin options. The edit fields show top, right bottom, left. If you enter a value of 20 or whatever number you like into these fields (anywhere the padding and margin fields appear) then nothing happens. If you enter the number followed by px, then the padding works. So 40px works and 40 does not work.
This may be the intended behavior but it's not usual with Page Builder. In other places you can enter 100 and the % is added or you can enter colours as FFFFFF and the hash # is added. Either way, I spent hours adding values to these padding fields and got nowhere until for some reason I added the px.
I do really like SP Page Builder but there are a few anomalies.
