My weird problem got solved by using Installer (.exe) instead of Portable (.zip).
My Home Button now shows in screen. Hopes to help anyone if get this circumstance.

First, very appreciate the Fire Toolbox, which allows us using Fire HD tablets with great and joyful experience. Second, sorry for my English, as it is not my native language.
Recently I got 2 new fire tablets from Amazon during Early Black Friday promotion. The Fire HD 10 plus running with Fire OS 7.3.2.1 surely works great with Toolbox V30.0. Another HD 10 (not plus version) running with Fire OS 7.3.2.4 works fine with Toolbox V30.0 except one weird problem.
Fire OS 7.3.2.4
My Steps: Custom Launcher > Nova launcher > Custom Navbar Button > Automate
After installation of Nova launcher (before Automate), at the bottom of tablet, my Home Button always disappeared but with Back and Menu Buttons still appeared. Fortunately, both 3 buttons work fine, just the Home Button visibly hidden in screen. No matter I reboot my tablet or Factory reset and reinstall different custom launcher, the Home Button will not appear.
Anyway to get my Home Button visibly back? Thank you for your precious help.
Moreover, when I tried “disable OTA update”, Toolbox recommends me to backup system before doing it. Is it the one shows in Page 2 in Toolbox menu? When I clicked it, it seems like backing up my device information like model and S/N in txt file.
