Problems converting certain layouts
Operating system version
Description of the issue
After doing a multi-file conversion from 11 to 12, a couple of layouts are quite a mess. One layout in particular has chunks of text pasted into it from a PDF form. The fields, which are not data fields, all show up having borders when none are specified. I have another layout in the same file which is similar in terms of source material and it's perfect. These files have worked in 8,9,10 and 11 without a problem. I reconverted the particular file too. No difference. As well, the conversion log is spotless.
Steps to reproduce the problem
Convert as above.
Layout should appear as before.
