Adding new items to accordion causes an unhandled exception error?

Question

I had an unhandled exception error trying to add new items to an accordions source in a project written in vb.net. The XAML for the accordion will cause the page to crash once I add an item to it. I believe this to be size related as some items will not load correctly (smashed together and certain size changes cause distortion). I have an image below to show what it looks like without the button but most of the other controls enabled. Note: remember to maximize the window to see the right side of the flip view and click the right arrow to go to manual where the accordion is.

The above image does not have the button enabled or a label but normally the its only the button that causes the program to generate an unhandled XAML error.

I believe it to be a resize  problem as stated above because I am using the data template in my xaml code for the syncfusion accordion control. Please use all of the xaml in my provided code example especially for the page named evaluateitem. You can remove the one flipciew item that has no manual evaluation in it but I have another xaml view for mobile so no need to resize everything.

I forgot to mention please enable the button that was commented out called BtnAddCondition and it might give you the error and I forgot to reenable that because it caused the error and I was backtracking. Do this using your current code. If it fails to produce an error I will send you a video in tomorrows attachment.

If it fails to produce an error I will send you a video in tomorrows attachment.Its seems the width was not properly set on my second relative panel in the datatemplate for the sfaccordion control (I had it too small). In addition, I removed and added a new button to the project and copied code over and the error went away. Weird. I am still have problems with new items being added to the accordion control. So, I believe it is still erroring out. Give me till later and I will upload a newer copy of the program if need be.

Nevermind, this is solved turned out to be a sizing problem and I fixed it. I need to set vertical alignment to stretch in some places.
