Hi Miguel,
Enterprise based on Warp7 framework, if you change the custom logo module, you need to switch the Joomla editor to codemirror or none first before changing.
For this case, I guess the rich editor like Tinymce or jce added the p tags for image that why it didn’t stick correctly. Could you please switch the editor to codemirror then check it ? Refer https://yootheme.com/support/question/88056#answer-255714
