in october i found an issue regarding the completion filters. If i declare a local variable and later use it, the completion popup don't show this variable. After installing the release build i found that this issue isn't fixed until now. I had reported an issue in YouTrack (https://youtrack.jetbrains.com/issue/RSRP-426561) for this and just upgraded it with my latest investigations. I get the issue in two cases: if i declare a variable with the "var" keyword and when i declare a variable of an enum type. If i disable the completion filters in the options, the popup works as expected.
