TeXstudio: excessive autocomplete

When I'm working in a math environment and I want to type something like \sec^2x, as soon as I type the ^ after the \sec, it autocompletes the \sec to \section. Or when I'm working in a tikzpicture environment and I want to type rotate = 90, it will autocomplete rotate = to rotate around x= as soon as I type the =. Is there a way to stop auto completion for specific commands? I don't want to give up the automatically putting the \end{} for whatever environment I'm working in.

Edit: I'm working in TeXstudio version 4.7.2. Some examples are I'm writing out some Pythagorean Identities:

\[\tan^2\theta=\sec^2\theta-1\] 

Or I'm drawing a diagram and want some nodes rotated:

\begin{tikzpicture} \draw (0,0) -- (0,3) -- (3,0) -- (0,0); \node[anchor = south, rotate = 90] at (0,1.5) {Silo}; \node[anchor = south, rotate = -90] at (0,1.5) {50 feet}; \node[anchor = north] at (1.5,0) {Shadow}; \node[anchor = south] at (1.5,0) {$L$}; \node[anchor = south east, xshift = -.4cm] at (3,0) {$\theta$}; \end{tikzpicture} 

I hope this clarifies things.

Well we're dealing with the opposite and adjacent, so we use tangent. \begin{align*} \tan\theta &= \dfrac{50}{L}\\ L &= \dfrac{50}{\tan\theta} = L(\theta) \end{align*} Part 1 done. We have the function. Now we just substitute the values into the function. For $10\degs$, $L(10) \approx 283.56$ feet. For $30\degs$, $L(30)\approx 86.60$ feet. For $50\degs$, $L(50)\approx 41.96$ feet. \end{Ex} \end{document}
