Error in log : Illegal string offset

General

I’ve recently seen in our error_log the following problem. Site is running ok but I don’t know if I have to investigate about it or just let it like that ?

PHP message: PHP Warning: Illegal string offset ‘image_y’ in ******/var/cache/templates/backend/00dab6c06e0a31cd5347466a912eaaa83e6c8031_2.tygh.presets.tpl.php on line 84

It’s just warnings so it shouldn’t hurt functionality.

I’d probably clear the cache (template cache in particular) and see if the warnings return.
