I would recommend to remove the brackets and add sub " " to elements with a superscript. You will see that the formatting varies.

Issue is with glyphs found in default OpenSymbol font used for the formula editor.

Bug 103740 will replace OpenSymbol's over weight plus sign. And the issue with the minus actually looks to be that the base line for the sm math module overbars are mispositioned, but the minus glyph could also be adjusted upward.  Would depend on the baseline used with the other operators in the font.

Meanwhile, if you use another font with Math symbol coverage (e.g. STIX, Asana Math, Noto Sans Symbols, or DejaVu Math TeX Gyre) may have more appealing layout.  Done from Tools -> Options -> Fonts: Apply replacement table check box and setting a replacement for OpenSymbol.  STIX have pretty good alignment across the operators and the Overbars.
