[Text Box changes into multiple text boxes]

I am having a major problem with text boxes in Affinity 2. I created a document with a text box. Within it, I had 8 subpoints, numbered 1-8, but they were all part of the same text box. I saved and closed the document, and the next time I opened it up, Affinity had separated each one of those lines into its own individual text box. You can see from the attached picture that it even splits sentences into two different text boxes if the sentence goes to the next line. This has now happened multiple times on multiple different documents. I have used Affinity for two years and have never had this problem, so I'm wondering if it's an Affinity 2 bug? I'm about to start a 190-page project and I cannot have this issue continue or it would be an absolute nightmare. I'm wondering if I should go back to Affinity 1 or if there is some setting I can fix on Affinity 2? Does anyone have any idea?
