After updating to v2.2.3, the following code

```
{\mu,\nu,\rho,\sigma}::Indices(vector).
{\partial{#}}::PartialDerivative.
connection := \Gamma^{\mu}_{\nu\rho} = 1/2 g^{\mu\sigma} ( \partial_{\rho}{g_{\nu\sigma}} + \partial_{\nu}{g_{\rho\sigma}} -\partial_{\sigma}{g_{\nu\rho}} );
```

will spit out

$$
\Gamma^{\mu}\,*{\nu \rho} = \frac{1}{2}g^{\mu \sigma} \left(\partial*{\rho}{g*{\nu \sigma}} \oplus \partial*{\nu}{g*{\rho \sigma}}-\partial*{\sigma}{g_{\nu \rho}}\right),
$$

it's wrong. And the following code

`ex:=\sin(\varphi)**2 \sin(\theta)**2;`

will give

$$ {\sin\left(\varphi\right)}^{2} {\left(\sin{\theta}\right)}^{2} $$

the result is also strange.
