Sogou Input cannot input the typed letters when press shift

Version: 1.0.207 Platform: Windows x64 10 and 11

Describe the problem: Hi team, I am using Sogou Input (搜狗输入法). I often need to switch between English and Chinese while typing. Sometimes I need to type in English, and after I have tapped some letters, I realize that I forgot to use Shift at the beginning to switch the input method to English mode. In this case, I used to press Shift to switch to English mode and at the same time get the letters I've already typed onto the screen, and this works on web pages and Microsoft Office softwares. However, in tabby, if I press Shift, the typed letter disappears and I have to type it again. This issue is limited to Sogou Input, but not to the Microsoft Pinyin.
