Autocorrect-Replace-New no longer accepts entires. Out of space?

Version: (x86) in Windows 7. I use Autocorrect extensively to turn special words into code. It has stopped accepting new entries. It seems to work; goes through the “New” entry dialogue flawlessly. But it isn’t saved, doesn’t work and doesn’t appear in the table the next time it’s opened. Entries that are there continue to work. Is there a limit to the size of the table that, perhaps, I’m bumping up against? The first time I tried today, it worked for the first time in a week or so–one entry and only that one entry. Again not accepting new entries after that.

Hello - not a developer but if I understand and libreoffice/core - main, development code repository right, then there is a limit of 2^32=4294967296 entries per language

Solved problem myself
