If I were to troubleshoot this issue, here's what I would do:
To start, I would examine the empty space closely:

Upon closer inspection, it appears that the height of the menu should not be 48 pixels. Next, I would analyze the Home link:

Based on my observation, the height seems to be too large for a standard menu item but smaller than 48 pixels. Moving forward, I would trace back to identify the specific element causing the excessive height:

After pinpointing the problematic element, I would delve into its styles to locate the root cause:

Upon examining the code in `navbar.less`, I noticed the following snippet:
.navbar {
min-height: 50px;
}
To resolve this issue, you can either override this globally or specifically as required in a stylesheet after bootstrap:
// Globally
.navbar {
min-height: 10px; // Or any desired value
}
// Specifically (based on your code)
.rgo_wrapper .navbar {
min-height: 10px; // Or any desired value
}
