I had to change the names (essentialy, every taxonomy term I created had a serial number followed by title - e.g. 1. This 2. That 3. This and that). I had to change some serial numbers in taxonomy, and I did it. After that, I had some problems. Every taxonomy term and seach on page is working properly, all items are showing with taxonomy terms and everything about that is ok. But for some reason, on Tainacan admin page, I miss one taxonomy term in filter section. I can find that taxonomy term in TAXONIMIES section, but it is missing in filter section (when expanded too). Screenshot here: ![image7](https://global.discourse-cdn.com/free1/uploads/tainacan/original/2X/c/cd1636d717d1efb844e08feeef215376631f20ef.jpeg) Also, when using option EDIT SELECTED ITEMS IN SEQUENCE i get strange error. Screenshots provided: ![image8](https://global.discourse-cdn.com/free1/uploads/tainacan/original/2X/f/f05176b1a0c7f9c1e97e6540bbcdfc60e9555d27.jpeg) ![image9](https://global.discourse-cdn.com/free1/uploads/tainacan/original/2X/a/a9a5dc42bf7cebd9c5c150a793c1b8a9ce5252d4.jpeg) I must point out that all cleared all cache from browsers, and also from Wordpress. I tried to delete filter and create another one, but that one taxonomy term still missing. I did not delete that taxonomy term, and created a new one, that I will leave as last option (it is not problematic, I have only 4 items with that taxonomy term). What do you think? tnx 🙂 ---

OK, I found solution for filters, I just changed SORT BY on that page and missing filter appeared, but that error still persists. ---

Hey @Vedran_Serbu sorry for the late reply. About that 400 error, it is bug. Thank you for reporting this, I just found the cause and will submit a fix later this week 😃 ---
