Old tables not shown

Hi Tobias,

I’ve some trouble with my old tables on our chess website. Since two weeks or so I get the following errors/warnings on pages with old tables. After updating the tables, they’re not shown anymore. I can’t explain why, hopefully you can?! The content is also displayed in red… Any ideas? Here ist one screenshot: https://files.bueroparallel.de/8TV267/TXMfhRlorX

Here is one site with the warnings/errors:

Here the site after editing the tables (just changes some words and saved it again; also tried to copy the table with the same content, but it doesn’t work):

Thx for your help,
Dennis
