Search Regex Error

The Plugin works (including using presets), but I get the error below when clicking on the Presets Tab. The error occurred after I used the option "Save search as new preset." Before that, i.e. no presets available, there was no error when clicking on the Presets Tab. ``` Plugin: 3.1.0 WordPress: 6.6.2 (single) PHP: 8.0.30 4294967296 300s Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:131.0) Gecko/20100101 Firefox/131.0 JavaScript: https://olfm.jansson-fam.se/wp-content/plugins/search-regex/search-regex.js REST API: https://olfm.jansson-fam.se/wp-json/ Query: ?page=search-regex.php&sub=options TypeError: s is null Hl@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:6:18800 tr 7435/ql<@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:6:20089 u@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:2:91562 tbody table 7435/$l<@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:6:22521 u@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:2:91562 wu@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:25:2374 Es@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:4:2715 div qi@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:2:187185 7435/Pu<@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:28:742 u@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:2:91562 pe@https://olfm.jansson-fam.se/wp-content/plugins/search-regex/build/search-regex.js?ver=3.1.0-51f0031aa4f8328cac5ce3f9a9d5b9e9:2:93507 Au ```
