[NSFW] Case-Insensitive option is not working on BSR v1.4.6

Hello, I have a problem with Case-Insensitive option of BSR. I tested both versions, 1.4.6 and 1.4.5 and it looks like new update contains an error with Case-Insensitive search and replace. I tested it out on multiple sites (with different themes, with(out) ACF, Elementor etc).

Example of testing:
I created a Production environment with a website template and staging environment with the same template and same setup as production. On production, I have BSR v1.4.6 and on staging, I deactivated v1.4.6 and installed & activated v.1.4.5

On production (BSR v1.4.6):
– Search term 1: getting 46 results found inside wp_postmeta (31) and wp_posts (15) tables
– Search term 2: getting 8 results found inside wp_postmeta (5) and wp_options (3) tables
– Search term 3: getting 39 results found inside wp_postmeta (26) and wp_posts (13) tables

On staging (BSR v1.4.5):
– Search term 1: getting 72 results found inside wp_postmeta (35), wp_posts (31), wp_gf_form_meta (1) and wp_rank_math_analytics_objects (5) tables
– Search term 2: getting 12 results found inside wp_postmeta (5), wp_options (4) and wp_usermeta (3) tables
– Search term 3: getting 47 results found inside wp_postmeta (28), wp_posts (17) and wp_rank_math_analytics_objects (2) tables

I tried with multiple sites/templates with the same testing method and results are similar.

All these searches were made with the “Case-Insensitive” option marked. If I try to search the same terms with uppercase letters, I am able to see the rest of the search results, but these are not showing with the “Case-Insensitive” option.

I tested to see if it’s up to some conflict with other plugins, but search results are the same on v1.4.6 even after deactivating any/all plugin(s).

Did anyone else notice the same? I’m using BSR quite a lot on a daily basis and I really hope this will be sorted out as soon as possible.
