variable AND following with a list of variables with OR

Experienced Tasker user here. When there is Task Action If/Then that using both AND, and OR (such as, when there is Global Variable and there is AND that following with a list of Global Variables with OR, then it seems there is one bug in Tasker. Apparently, it didn't recognize the first variable when following with AND and then list of OR values. It does appear to be bug of Tasker as I am writing here, so will show example below in case if I am overlooking something so you can see for yourself.

%ElectVarCurTimeShPatternVar < 10 AND %ElectPriceVarCurTimeVar1 ~ 0 OR %ElectPriceVarCurTimeVar1 ~ 10 OR %ElectPriceVarCurTimeVar1 ~ 11 OR %ElectPriceVarCurTimeVar1 ~ 12, etc., until variable value 23.

It went through if/then condition although %ElectVarCurTimeShPatternVar value was more than 10. Workaround is to add the AND with separate IF/THEN  before the IF/THEN with list of OR values. I'm wondering if I may have some bugs elsewhere that trigger only in some rare cases because of this apparently current Tasker bug/limitation.

Using version 5.9.3.

(Also, by the way, when the Tasker version becomes 6+?. After 5.9, when hitting higher, it should switch to number 6. Just one observation of confusion from quick look of changelog. I think it's better if coninuing with 5.9414 rather than going back to 5.1. Currently, it seems from version number comparing 5.9.3 with current version at Play Store that I am in the future, ha!)
