Fixed bug on the factor levels control being hidden in some dialogs

[N-thony]

Fixes #7269
@rdstern I had a quick discussion on this with @ChrisMarsh82 and then found that the problem was more general mainly under the following dialogues and ucrInputFacotrLevels itself:

• dlgCalculateTreatementDifferences
• dlgClimaticDataEntry
• dlgCalculateTreatementLines
• dlgSetupForDataEntry
• ucrInputFacotrLevels
  To fix this, we just set the AutoSize property to False and also adjusted the Size of ucrInputFacotrLevels and it corresponds to the above dialogues.

Please take a look. Thanks.

@N-thony great. I have checked where I found the problem, and that is fixed. I also looked at the setup for data entry and that also seems fine, but I didn't see it before.
I have not checked others, because you just give the function names, so I'm not quite sure which dialogues, nor what I should look for. But I assume the problem is solved, and am very relieved. Over to @lloyddewit or @shadrackkibet for second approval and merge.
That's a relief!

@africanmathsinitiative/developers I think we might have this kind of problem in other places. Can we get volunteers to quickly check and report on dialogs with this kind of problem? Let us get volunteers by menu.
