Conflict with Polylang

When items are set to “Show on checked pages”, they do not output at all – if I have Polylang activated. This only appeared as an issue recently, likely with an update to WP or Polylang. Once Polylang is deactivated the Simple Link List outputs again.

Oddly, if I instead choose to “Hide on checked pages”, or if I choose a particular language (English) to show the Simple Link List on… then it works, even with Polylang activated.

Any help is appreciated, but I cannot share the URL yet, site is not yet public.
