I am a newbie on this site. I am NOT a SharePoint developer or admin by trade. I have accumulated this job with on the job training. I am by far not an expert or claim to be.
My issue is this, when I add an Excel Access Web Part (without pointing to a file), my SharePoint pages and site looks fine with the custom top navigation bar and colors. However, when I attach the excel file in the Web Part, I lose the customization in the Top Navigation Bar. This only happens with the Excel Web Part. No other web part does this.
Here is how the navigation looks like before and after.
I have asked our developer and IT team without any luck. I have had my IT contact Microsoft without any luck too. So, if anyone has any ideas please let me know, we are willing to explore any options.
Thank you in advance for your help on this issue.
