Why is text being deleted by IMDb within a submitted Real Life Quote?

I have twice submitted a Real Life Quote for Robert Gottlieb (VI) with the following phrase in part of its first sentence, "... who couldn't be more eager for suggestions... [yet is] one of those writers for whom," (updates 230313-062221-496000 and 230315-033938-869000). The first submission was a few characters over the 500-character limit due to the square bracket markup syntax I used to produce a link to the writer in question, which I noted in my explanation. When IMDb accepted the quote, it appeared as, "... who couldn't be more eager for suggestions... is] one of those writers for whom,". I thought the deletion of the "[yet " might have been an arbitrary edit to bring the quote below 500 characters, so I deleted the update and resubmitted a version with fewer than 500 characters which restored the "[yet ". Yet the second accepted version still appears as "... who couldn't be more eager for suggestions... is] one of those writers for whom,". Visually and grammatically, the phrase makes no sense with this deletion. Please have someone restore the "[yet " in this phrase. Thanks in advance. Note that the quote would go well over the 500-character limit if it were to include the full phrase from Gottlieb's original quote which I've replaced with the "yet is".
