You’re not alone! This is a known issue, and we’re currently testing a fix to make sure it works perfectly before releasing it.
Here’s the scoop:
Unlike Primavera P6, where the Activity column is fixed, Microsoft Project (MPP) offers more flexibility. While this is great for customising your schedules, it also means that XER Toolkit doesn’t always know which column holds your activity data.
The upcoming fix will solve this by simply asking you to select the correct column for your activities when importing your MPP schedule. This straightforward approach will make sure your activities appear just as they should!
We’re putting this solution through its paces, and we’ll announce as soon as it’s ready. Stay tuned—it’s not far off! 
If you need help in the meantime, just give us a shout. We’re here to help!
