Reusable Text Blocks removes certain fields

I’ve used Text Blocks for quite some time. Recently, I noticed certain fields within my pages were not saving or displaying properly. Our web host determined it was due to the Reusable Text Blocks. As you can see in the link provided, our events list Duration, Price, Departs, as well as the large image on the left. Earlier this week, none of these fields will save while working on the page while Text Blocks is active. The image field will appear blank and the other fields do not appear. However, if I deactivate Text Blocks and enter the fields, they all save. This does cause other Text Blocks elements to disappear. Once I have saved all the elements and then reactivate Text Blocks, everything appears as desired. Do you know why this occurs?
